The Cow - 2:177
It is not good that you turn your faces towards the east or the west. The righteous are those who believe in Allah, the Last Day, the angels, the Book and the Prophets, and they give freely to relatives, orphans, the needy, the stranded, the beggars, and to free the slaves, and they observe the prayer, and pay the zakat, and keep their word when they contract, and they resist hardship, distress and oppression. It is they who are the righteous, and it is they who are the virtuous.
The believers also fulfill their promises:
The Cattle/6:152
Do not approach the property of orphans until they reach the age of maturity. Measure and weigh accurately. We do not burden a person with what he is not able. When you speak, be truthful even against your relatives. Keep your promise to Allah. These are His admonitions to you that you may take a lesson.
وَلَا تَقْرَبُوا مَالَ الْيَت۪يمِ اِلَّا بِالَّت۪ي هِيَ اَحْسَنُ حَتّٰى يَبْلُغَ اَشُدَّهُۚ وَاَوْفُوا الْكَيْلَ وَالْم۪يزَانَ بِالْقِسْطِۚ لَا نُكَلِّفُ نَفْساً اِلَّا وُسْعَهَا وَاِذَا قُلْتُمْ فَاعْدِلُوا وَلَوْ كَانَ ذَا قُرْبٰىۚ وَبِعَهْدِ اللّٰهِ اَوْفُواۜ ذٰلِكُمْ وَصّٰيكُمْ بِه۪ لَعَلَّكُمْ تَذَكَّرُونَۙ
The Coalition/33:15
They had promised Allah before that they would not turn their backs and flee. Every promise made to Allah will be questioned.
وَلَقَدْ كَانُوا عَاهَدُوا اللّٰهَ مِنْ قَبْلُ لَا يُوَلُّونَ الْاَدْبَارَۜ وَكَانَ عَهْدُ اللّٰهِ مَسْؤُ۫لاً
The Thunder/13:20
Those who fulfill their promise to Allah and do not break the covenant.
اَلَّذ۪ينَ يُوفُونَ بِعَهْدِ اللّٰهِ وَلَا يَنْقُضُونَ الْم۪يثَاقَۙ
The Stories/28:27
"He said, "I want to marry you to one of my daughters on condition that you work for me for eight pilgrimages. You can make it ten (years) if you wish. I do not want to cause you any hardship. If Allah wills, you will find me a righteous person."
قَالَ اِنّ۪ٓي اُر۪يدُ اَنْ اُنْكِحَكَ اِحْدَى ابْنَتَيَّ هَاتَيْنِ عَلٰٓى اَنْ تَأْجُرَن۪ي ثَمَانِيَ حِجَجٍۚ فَاِنْ اَتْمَمْتَ عَشْراً فَمِنْ عِنْدِكَۚ وَمَٓا اُر۪يدُ اَنْ اَشُقَّ عَلَيْكَۜ سَتَجِدُن۪ٓي اِنْ شَٓاءَ اللّٰهُ مِنَ الصَّالِح۪ينَ
The Stories/28:28
"He said, "This is a contract between you and me. Whatever term I fulfill, there will be no enmity against me. Allah is the guarantor of what we have spoken."
قَالَ ذٰلِكَ بَيْن۪ي وَبَيْنَكَۜ اَيَّمَا الْاَجَلَيْنِ قَضَيْتُ فَلَا عُدْوَانَ عَلَيَّۜ وَاللّٰهُ عَلٰى مَا نَقُولُ وَك۪يلٌ۟
The Stories/28:29
"When Moses fulfilled that term and set out with his family, he saw a fire on the slope of Tur and said to his family, "Stay here, I have seen a fire; perhaps I will bring you news of it or a fire-wood so that you may warm yourselves with it."
فَلَمَّا قَضٰى مُوسَى الْاَجَلَ وَسَارَ بِاَهْلِه۪ٓ اٰنَسَ مِنْ جَانِبِ الطُّورِ نَاراًۚ قَالَ لِاَهْلِهِ امْكُثُٓوا اِنّ۪ٓي اٰنَسْتُ نَاراً لَعَلّ۪ٓي اٰت۪يكُمْ مِنْهَا بِخَبَرٍ اَوْ جَذْوَةٍ مِنَ النَّارِ لَعَلَّكُمْ تَصْطَلُونَ
The Coalition/33:22
"When the believers see the parties (ready to attack), they say, "This is what Allah and His messenger promised us. Allah and His messenger have spoken the truth."This (dangerous situation) only strengthened their faith and submission."
وَلَمَّا رَاَ الْمُؤْمِنُونَ الْاَحْزَابَۙ قَالُوا هٰذَا مَا وَعَدَنَا اللّٰهُ وَرَسُولُهُ وَصَدَقَ اللّٰهُ وَرَسُولُهُۘ وَمَا زَادَهُمْ اِلَّٓا ا۪يمَاناً وَتَسْل۪يماًۜ
The Coalition/33:23
There are such of the believers who have fulfilled their promise to Allah. Some of them fulfilled their pledge (became martyrs) and some of them are waiting. They have never wavered.
مِنَ الْمُؤْمِن۪ينَ رِجَالٌ صَدَقُوا مَا عَاهَدُوا اللّٰهَ عَلَيْهِۚ فَمِنْهُمْ مَنْ قَضٰى نَحْبَهُ وَمِنْهُمْ مَنْ يَنْتَظِرُۘ وَمَا بَدَّلُوا تَبْد۪يلاًۙ
Those Who Set The Ranks/37:101
So We granted him (Abraham) a mild-tempered son.
فَبَشَّرْنَاهُ بِغُلَامٍ حَل۪يمٍ
Those Who Set The Ranks/37:102
"When he reached the age of working with him, he said, "My son,"he said, "I dreamed that I should slaughter you. What do you think?""My father,"he said, "do as you are commanded. If Allah wills, you will find me patient."
فَلَمَّا بَلَغَ مَعَهُ السَّعْيَ قَالَ يَا بُنَيَّ اِنّ۪ٓي اَرٰى فِي الْمَنَامِ اَنّ۪ٓي اَذْبَحُكَ فَانْظُرْ مَاذَا تَرٰىۜ قَالَ يَٓا اَبَتِ افْعَلْ مَا تُؤْمَرُۘ سَتَجِدُن۪ٓي اِنْ شَٓاءَ اللّٰهُ مِنَ الصَّابِر۪ينَ
Those Who Set The Ranks/37:103
So they both surrendered and he slaughtered him on his forehead.
فَلَمَّٓا اَسْلَمَا وَتَلَّهُ لِلْجَب۪ينِۚ
Those Who Set The Ranks/37:104
"We called out to him, "Abraham!"
وَنَادَيْنَاهُ اَنْ يَٓا اِبْرٰه۪يمُۙ
Those Who Set The Ranks/37:105
"You have fulfilled your dream."This is how We reward the good."
قَدْ صَدَّقْتَ الرُّءْيَاۚ اِنَّا كَذٰلِكَ نَجْزِي الْمُحْسِن۪ينَ
The Victory/48:10
Those who pledge allegiance to you have pledged allegiance to Allah. Allah´s hand is upon their hands. Whoever breaks his pledge breaks it against himself. And whoever fulfills his promise to Allah, We shall give him a great reward.
اِنَّ الَّذ۪ينَ يُبَايِعُونَكَ اِنَّمَا يُبَايِعُونَ اللّٰهَۜ يَدُ اللّٰهِ فَوْقَ اَيْد۪يهِمْۚ فَمَنْ نَكَثَ فَاِنَّمَا يَنْكُثُ عَلٰى نَفْسِه۪ۚ وَمَنْ اَوْفٰى بِمَا عَاهَدَ عَلَيْهُ اللّٰهَ فَسَيُؤْت۪يهِ اَجْراً عَظ۪يماً۟
The Victory/48:18
Allah is pleased with the believers who pledged allegiance to you under the tree. He knew what was in their hearts and sent down peace on them and rewarded them with an imminent victory.
لَقَدْ رَضِيَ اللّٰهُ عَنِ الْمُؤْمِن۪ينَ اِذْ يُبَايِعُونَكَ تَحْتَ الشَّجَرَةِ فَعَلِمَ مَا ف۪ي قُلُوبِهِمْ فَاَنْزَلَ السَّك۪ينَةَ عَلَيْهِمْ وَاَثَابَهُمْ فَتْحاً قَر۪يباًۙ
The Ways of Ascent/70:32
They are trustworthy, true to their word;
وَالَّذ۪ينَ هُمْ لِاَمَانَاتِهِمْ وَعَهْدِهِمْ رَاعُونَۖ
The Man/76:7
They fulfill their promises and fear a Day that is exceedingly evil.
يُوفُونَ بِالنَّذْرِ وَيَخَافُونَ يَوْماً كَانَ شَرُّهُ مُسْتَط۪يراً

لَيْسَ الْبِرَّ اَنْ تُوَلُّوا وُجُوهَكُمْ قِبَلَ الْمَشْرِقِ وَالْمَغْرِبِ وَلٰكِنَّ الْبِرَّ مَنْ اٰمَنَ بِاللّٰهِ وَالْيَوْمِ الْاٰخِرِ وَالْمَلٰٓئِكَةِ وَالْكِتَابِ وَالنَّبِيّ۪نَۚ وَاٰتَى الْمَالَ عَلٰى حُبِّه۪ ذَوِي الْقُرْبٰى وَالْيَتَامٰى وَالْمَسَاك۪ينَ وَابْنَ السَّب۪يلِ وَالسَّٓائِل۪ينَ وَفِي الرِّقَابِۚ وَاَقَامَ الصَّلٰوةَ وَاٰتَى الزَّكٰوةَۚ وَالْمُوفُونَ بِعَهْدِهِمْ اِذَا عَاهَدُواۚ وَالصَّابِر۪ينَ فِي الْبَأْسَٓاءِ وَالضَّرَّٓاءِ وَح۪ينَ الْبَأْسِۜ اُو۬لٰٓئِكَ الَّذ۪ينَ صَدَقُواۜ وَاُو۬لٰٓئِكَ هُمُ الْمُتَّقُونَ
