A unique feature that we find in the famous books of hadeeth like the sihaah sittah i.e. Saheeh Bukhaari, Saheeh Muslim, Tirmizi, etc. is that when the authors recorded the ahaadeeth, they always wrote the durood on Nabi (sallallahu ‘alaihi wasallam) in full. They never used abbreviations as we find nowadays like ‘S.A.W.’. It didn’t matter even if the durood took up a third of the kitaab. Hence, we find that upon their demise, Nabi (sallallahu ‘alaihi wasallam) personally came to welcome and receive them. Thus, they lived for the sunnah and died for the sunnah.
Through the blessings of the ahadeeth and abundant durood, they were honoured during their lifetimes and even after death. The grave of Imaam Bukhaari (rahmatullahi ‘alaih) would give off a fragrant smell.
