Chapter: The Obligation To Follow Him (SAW)
Musa b. Talha reported: I and Allah's Messenger ( صلی اللہ علیہ وسلم ) happened to pass by people near the date-palm trees. He (the Holy Prophet) said: What are these people doing? They said: They are grafting, i. e. they combine the male with the female (tree) and thus they yield more fruit. Thereupon Allah's Messenger ( صلی اللہ علیہ وسلم ) said: I do not find it to be of any use. The people were informed about it and they abandoned this practice. Allah's Messenger ( صلی اللہ علیہ وسلم ) (was later) on informed (that the yield had dwindled), whereupon he said: If there is any use of it, then they should do it, for it was just a personal opinion of mine, and do not go after my personal opinion; but when I say to you anything on behalf of Allah, then do accept it, for I do not attribute lie to Allah, the Exalted and Glorious.
Rafi' b. Khadij reported that Allah's Messenger ( صلی اللہ علیہ وسلم ) came to Medina and the people had been grafting the trees. He said: What are you doing? They said: We are grafting them, whereupon he said: It may perhaps be good for you if you do not do that, so they abandoned this practice (and the date-palms) began to yield less fruit. They made a mention of it (to the Holy Prophet), whereupon he said: I am a human being, so when I command you about a thing pertaining to religion, do accept it, and when I command you about a thing out of my personal opinion, keep it in mind that I am a human being. 'Ikrima reported that he said something like this.
Anas reported that Allah's Messenger ( صلی اللہ علیہ وسلم ) happened to pass by the people who had been busy in grafting the trees. Thereupon he said: If you were not to do it, it might be good for you. (So they abandoned this practice) and there was a decline in the yield. He (the Holy Prophet) happened to pass by them (and said): What has gone wrong with your trees? They said: You said so and so. Thereupon he said: You have better knowledge (of a technical skill) in the affairs of the world.
