Khaarijah bin Zayd bin Thaabit Radiyallahu 'Anhu says that a group came to Zayd bin Thaabit (his father) and requested him to describe to them some facts about Rasulullah Sallallahu 'Alayhi Wasallam. He replied. "What can I describe to you of Rasulullah Sallallahu 'Alayhi 'Wasallam. (It is beyond my means to describe them). I was the neighbour of Rasulullah Sallallahu 'Alayhi Wasallam. (Therefore he was mostly present and knew many facts. He was also a writer of the wahi-revelation). When wahi was revealed to Rasulullah Sallallahu 'Alayhi Wasallam, he sent for me, I came and wrote it. (Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam always showed kindness, and made us feel at ease). Whatever we discussed, he discussed the same. If we discussed some worldly affairs, he also spoke of it. (It was not that he only spoke about the hereafter to us, and despised the talking of worldly affairs). When we spoke of the hereafter, he too spoke of the hereafter. When we began speaking of the hereafter, he described its events etc in detail). 'When we spoke of food, Rasulullah Sallallahu 'Alayhi Wasallam also spoke of it. (Its etiquette, benefits, tasty foods, foods that are harmful, etc. In the previous chapters many such commands of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam are mentioned. i.e. 'What a wonderful curry vinegar is'. 'Use olive oil, it is from a mubaarak tree'. etc.). All this I am saying are facts on Rasulullah Sallallahu 'Alayhi Wasallam'".
