Abu Uthman (Radhiyallaho anho) says: "I was once sitting under a tree with Salmaan (Radhiyallaho anho). He caught hold of a dry branch of the tree and shook it till all its leaves fell off. He then said to me, "0, Abu Uthman! (Radhiyallaho anho) Will you not ask me why I am doing this?" "Do tell me," I entreated. He said, "The Prophet of Allah had done exactly like this before me, while I was with him under a tree. He caught a dry branch of it and shook it, till all its leaves fell off".
At this he said: "0, Salmaan! (Radhiyallaho anho) will you not ask me why I am doing this?' I replied: 'Do tell me why you are doing this?' He remarked: "Verily when a Muslim takes wudhu properly and then observes his salaat five times a day, his sins fall off just as these leaves have fallen off. He then recited the following verse of the Holy Qur'an:
"Establish salaat at the two ends of the day, and at the approaches of the night.
Verily, good deeds annul ill deeds. This is a reminder for the mindful." (Qur'an 11:114)
The behaviour of Salmaan (r.a) in the above Hadith displays the profound love which the companions had for the Prophet (Sallallaho alaihe wasallam). They would often cherish the sweet memories of the time when the Prophet (Sallallaho alaihe wasallam) was living among them. They would, while quoting him, enact exactly what they had seen him doing at a particular moment.
IT IS REALLY VERY DIFFICULT TO COVER ALL THE TRADITIONS OF THE PROPHET (S.A.W).
