Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following:
Many of my children had passed away in infancy. When any child would pass away, and the mother (i.e. my wife) would weep, then I would (console her and) say to her, “Neither you, nor I, possess any good deeds. Insha Allah, all of this (grief that we are experiencing and sabr that we are exercising) will be combined on the Day of Qiyaamah and will be a means of removing the burden of our sins.”
(Qutbul Aqtaab Hazrat Sheikhul Hadith Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) pg. 509)
