Does one who prays at the end of the row, far from the ma'mum, take the ruling of one who prays alone?

Question:
Well, he says: If a man prays at the end of the row, O Shaykh Salih, and there is a distance between him and the ma'mum in the row, is the prayer considered the prayer of one who prays alone?

Answer:
No, as long as he is in line with the row, he is in the row by ruling. As for filling the gaps and keeping the rows tight, that is required, and the Prophet (peace and blessings be upon him) commanded it. But we do not say that his prayer is invalid if he is in line with the row, even if he is separated from it. Yes.
