In relation to this Ayah, Sadr ul Afazil, ’Allamah Maulana Sayyid Muhammed Na’eem-ud-Deen Muradabadi has said: Giving respite to the one who does not have the means to repay his debt or forgiving some of the debt or the entire debt is a great way of gaining great reward.
A blessed Hadith of Sahih Muslim states that the Holy Rasool has said: The one who gives respite to the one in debt (who does not have the means to repay it) or forgives the debt, Allah will give him the shade of his mercy on the day when there will be no shade other than the shade (given by) Allah The Holy Rasool has said: The one who likes that on the Day of Judgement, Allah Almighty saves him from sorrow, then he should give respite to the helpless person in debt or forgive his entire debt. (Muslim, pp. 845, Hadees 1563)
The pious saints of Islam did not just give respite to the ones in debt, but were also lenient in their demanding of the repayment. In fact, a lot of times, they would even forgive the debt entirely! As Sayyiduna Shaqeeq Bin Ibrahi says that one day, I was walking on a path with Imam A’zam Abu Hanifah and he was going to inquire after an ill person.
Imam Abu Hanifah saw a man coming from a distance. This man quickly hid from Imam Abu Hanifah and changed his path. Imam e A’zam called him by his name and said: ’Walk the same way you were walking before, do not change the course.’ When he realised that Imam e A’zam has recognized him and called him, he became very embarrassed and stopped where he was. Imam e A’zam asked him: ’Why did you change your path?’ He replied: ’Huzoor! It has been a substantial time since I owed you 10,000 diagrams and I have not been able to repay you.
