Q If Asr salaah was performed on the early time (shafee). Must it be repeated? Do we all not have to follow one way? To convince my brother to pray, can I have him do it at a time he wants to pray, and then I repeat my own prayer. He claims unity must allow us to all pray at one time…
A. To intentionally do something one does not believe to be correct and knowing a thing is wrong to do would be a sin. To do an act out of necessity would allow for its permissibility.
It would be correct to perform asr at Misle-awwal if ones mazhab allows for it. If a person refuses to follow a mazhab whilst lacking knowledge of Islam in its genuine form and wishers to do as they chose, then naturally such a person can do they choose.
If you intentionally performed a salaah on the wrong time, then merely do a repeat of that given salaah.
If the choice is between performing and not prayers, then they can perform their asr salaah at either misle-awal (time period when the shadow of an object is single) or Mislain (when the shadow of an object doubles.) Since Islam is not about picking and choosing, for him to do as he desires without having the ability of making ijtihad would not be permissible.
Performance of prayer at a set time has nothing based of Hadeeth has noting to do with unity per se It is a matter linked to ijtihad, an act that can performed by a mujtahid! If your brother does not know this simple fact, then we think it best for him to follow a school of thought so as to aid his practice and understanding of religion in its simplest form.
Allah Certainly Knows best.
