Tafsir Al-Jalalayn: Al-Ma'aarij, Ayah 37

Is it not sufficient for one of you or for one of them that he puts his hand on his thigh, and then gives the salutation to his brother to his right and left sides.

I was sitting with my father and there was also a boy with him. He got up and then returned. So my father mentioned a tradition on the authority of Abu Hurairah from the Prophet (ﷺ) saying: If anyone ...

"When one of you gets up from his spot, then comes back, he has more right to it."

“When anyone of you puts on his sandals, let him start with the right, and when he takes them off, let him start with the left.”

None should make one'& brother stand and then sit at his place (and it was common with) Ibn Umar that when any person stood in the company (with a view to making room for him) he did not sit there.

“Pass it around to the right.”

No person should ask another person to stand at his place and then he should himself sit there, but he should simply say: Make room and accommodate.

"When one of you puts on sandals, he should first put in the right foot, and when he takes off he should take off the left one first. And he should wear both of them or take both off."

The best rows for men are the first rows, and the worst ones the last ones, and the best rows for women are the last ones and the worst ones for them are the first ones.
