Chapter 2, Verse 283, The Cow
سُوۡرَةُ البَقَرَة
۞وَإِن كُنتُمۡ عَلَىٰ سَفَرٖ وَلَمۡ تَجِدُواْ كَاتِبٗا فَرِهَٰنٞ مَّقۡبُوضَةٞۖ فَإِنۡ أَمِنَ بَعۡضُكُم بَعۡضٗا فَلۡيُؤَدِّ ٱلَّذِي ٱؤۡتُمِنَ أَمَٰنَتَهُۥ وَلۡيَتَّقِ ٱللَّهَ رَبَّهُۥۗ وَلَا تَكۡتُمُواْ ٱلشَّهَٰدَةَۚ وَمَن يَكۡتُمۡهَا فَإِنَّهُۥٓ ءَاثِمٞ قَلۡبُهُۥۗ وَٱللَّهُ بِمَا تَعۡمَلُونَ عَلِيمٞ
And if you are on a journey and cannot find a scribe, then let there be a pledge taken (mortgaging); then if one of you entrust the other, let the one who is entrusted discharge his trust (faithfully), and let him be afraid of Allah, his Lord. And conceal not the evidence for he, who hides it, surely his heart is sinful. And Allah is All-Knower of what you do.
Chapter 16, Verse 91, The Bee
سورة النحل
وَأَوۡفُواْ بِعَهۡدِ ٱللَّهِ إِذَا عَٰهَدتُّمۡ وَلَا تَنقُضُواْ ٱلۡأَيۡمَٰنَ بَعۡدَ تَوۡكِيدِهَا وَقَدۡ جَعَلۡتُمُ ٱللَّهَ عَلَيۡكُمۡ كَفِيلًاۚ إِنَّ ٱللَّهَ يَعۡلَمُ مَا تَفۡعَلُونَ
And fulfill the Covenant of Allah (Bai'a: pledge for Islam) when you have covenanted, and break not the oaths after you have confirmed them, and indeed you have appointed Allah your surety. Verily! Allah knows what you do.
Chapter 48, Verse 10, The victory
سورة الفتح
إِنَّ ٱلَّذِينَ يُبَايِعُونَكَ إِنَّمَا يُبَايِعُونَ ٱللَّهَ يَدُ ٱللَّهِ فَوۡقَ أَيۡدِيهِمۡۚ فَمَن نَّكَثَ فَإِنَّمَا يَنكُثُ عَلَىٰ نَفۡسِهِۦۖ وَمَنۡ أَوۡفَىٰ بِمَا عَٰهَدَ عَلَيۡهُ ٱللَّهَ فَسَيُؤۡتِيهِ أَجۡرًا عَظِيمٗا
Verily, those who give Bai'a (pledge) to you (O Muhammad ﷺ) they are giving Bai'a (pledge) to Allah. The Hand of Allah is over their hands. Then whosoever breaks his pledge, breaks only to his own harm, and whosoever fulfills what he has covenanted with Allah, He will bestow on him a great reward.
Chapter 74, Verse 38, The cloaked one
سورة المدثر
كُلُّ نَفۡسِۭ بِمَا كَسَبَتۡ رَهِينَةٌ
Every person is a pledge for what he has earned,
Chapter 3, Verse 76, The family of Imran
سورة آل عمران
بَلَىٰۚ مَنۡ أَوۡفَىٰ بِعَهۡدِهِۦ وَٱتَّقَىٰ فَإِنَّ ٱللَّهَ يُحِبُّ ٱلۡمُتَّقِينَ
Yes, whoever fulfils his pledge and fears Allah much; verily, then Allah loves those who are Al-Muttaqun (the pious - see V. 2:2).
