Because the hadith has appeared in the collection of Imam Bukhari then it should be duly respected. If the prophet never said that or if the chain of narration of that Hadith is weak, then it is o.k. not to follow it. Otherwise it is a very wise reply from the prophet of Allah and should be followed.
There are many other examples like that. I donot have reference but some one asked the prophet s.a.w.s. about the cleaning (washing) of the shoes. He replied that there is no need to wash them. Walking about purifies them.
There is another report about some kind of cheeze that was brought to the prophet s.a.w.s. and it was told that it was made (processed) with the fat (or some ingredient) of the swine. He cut a part of it and ate it.
I was faced with a difficult situation in China. I was a team leader and a guest there. In the evening we saw a big fried duck in the centre of the dining table. The Chinese hosts were very jubilant (happy) to offer us that speciality. My frineds (about ten of them) asked from they got the duck. The chinese replied that it was "Shoot (shot?) for you in the jungle".
All my friends being Muslims left the table and sat at the other table. I was left alone there. So what to do then?? The chinese were surprised and did not know what was going on. I told my friends to come back and co-operate. They refused.
So, I picked up the knife. I recited the Kalimah and cut a piece of the duck and I ate it there, alone. That was the best I could do then. It is in the Quran that any one who is put in some difficult situation but he is not rebellious nor habitual, then there is no sin on him. "Faman idhturra ghaira baaghin wa laa aadin, Flaa ithma Alaihi."
May Allah Forgive me if I did wrong. But this was a practical situation. I had no chance to consult any scholar.
