Is it permissible to prepare and arrange the shroud while in good health?

Question : Preparing the shroud before the illness. Yes.

Answer : This is also one of the trials. This is a bid'ah (religious innovation) because the Companions did not do it, and the Prophet (peace and blessings be upon him) did not do it. But this man wanted to seek blessing from the adhan of the Prophet (peace and blessings be upon him). For this reason, al-Bukhari (may Allah have mercy on him) had insight in this matter; he said: "Whoever prepared his shroud in the time of the Prophet (peace and blessings be upon him) was not rebuked for it. But after that, he is not cursed."
Before the severe crowding in the Sacred Mosque, people used to buy, I mean,
a lot of this. I don't know what they call it? No, no, no, is it called a "taqah"? I was afraid our language differs from yours. This "taqah" is sold in large quantities, meaning from here to beyond the mosque. They wash it with Zamzam water and spread it on the walkways, saying it is for seeking blessing. But, praise be to Allah, now the crowding has become a benefit; they cannot get it outside the mosque.
