Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hassan ibn Mahbub from Mu‘awiyah ibn ‘Ammar who has said the following: “Abu ‘ Abd Allah (a.s.), once, spoke to us and repeated the following phrase three times.

‘If one wishes that Allah provide him shadow on the Day when there will be no shadow except His shadow,’ and no one had the courage to ask him to explain, he (Imam) then said, ‘He should extend the due date of repayment of a loan for a borrower who has difficulty to pay back, or partially waive it in his (debtor’s) favor.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (6/163))
