People disagreed about it, some say that his prayer is valid and some say that it is not valid, and the one I refer to for a ruling in this case is that he either finds a way to enter the row or he does not find it, and if he does not find it, then he should indicate to a man from the people of the row that he should retreat to him. He did not resort to it due to his ignorance of the reward he has for that with God. This man’s prayer is valid, for he has feared God as much as he is able, and he cannot in this case do more than this. If he is able to do something of what we have mentioned and does not do it, his prayer is invalid, for the Prophet, peace be upon him, commanded those who were He prayed behind the row alone to repeat, and it is the hadith of Wabisa bin Ma’bad
