What is the ruling on an elderly, blind person quarreling to take a place in the first row? And are "the foremost [in faith], the foremost [in reward]" those who race to the first row, as mentioned in a noble Hadith?

It is not permissible for a man to make you stand up from a place you occupied before him, for Muslim narrated from the Prophet, peace and blessings be upon him, that he said: "None of you should make a man stand up from his seat and then sit in it." This prohibitive injunction establishes the right of priority for whoever occupies a permissible spot first. You are not obliged to stand up for him; rather, some jurists consider it disliked due to the selflessness involved in giving up a good position. As for the noble verse: {And the foremost are the foremost, those are the ones brought near}, there is no prophetic hadith that links it to competing for the first row. Some of the predecessors interpreted it as referring to those who are prompt in doing good deeds, such as hastening to the mosque and going forth in the way of Allah.
