مَن أقرَضَ مُؤمناً قَرضاً يَنتَظِرُ بهِ مَيسورَهُ كانَ مالُهُ في زَكاةٍ ، وكانَ هو في صَلاةٍ مِن المَلائكةِ حتّى يُؤَدِّيَهُ إلَيهِ.
Whoever gives a loan to a believer and waits until he is able, his money will be regarded as alms-tax, and the angels will pray for him until his loan is returned.
Thawab al-A'malp, p. 167, no. 4
