Ibn Majah

Hadith Commentary: Benefits and Issues: The Messenger of Allah (sallallahu alayhi wa sallam) instructed to recite the supplication for opening the gate of mercy when entering the mosque, because the word "mercy" (rahmah) is generally used in the Qur'an and Hadith for rewards and favors of the Hereafter and for religious and spiritual blessings. The mosque is a place for attaining religious, spiritual, and otherworldly blessings. And when leaving the mosque, he taught to ask Allah Almighty for His bounty and grace, that is, for sustenance, and for blessings in wealth and property, because the word "bounty" (fadl) is used for the granting and abundance of sustenance, wealth, and property. After performing the Friday prayer, Allah Almighty commands:
﴿وَابْتَغُوا مِنْ فَضْلِ اللَّهِ﴾ “Spread out in the land and seek the bounty of Allah.”
So, it is as if for the world outside the mosque, it is appropriate that a person should engage in the pursuit of sustenance. The main purpose is that whether a person is in the mosque or outside the mosque, wherever and whenever, the servant should not be heedless of Allah Almighty. In every place, his supplicating attention should be towards Allah Almighty.

Benefits and Issues:
Swearing oaths by way of hints, allusions, or equivocations (tawriyah) in order to resolve disputes among Muslims is in no way beneficial or permissible.
Rather, it is unlawful.
However, if there is a confrontation with disbelievers (kuffar) or oppressors (zalimun), then concession is granted.

Benefit:
This means that if someone swears an oath and makes an ambiguous statement, intending a meaning that is true, but the listener does not understand that meaning and instead understands a meaning which, according to him, is incorrect, then this will be considered a false oath.
The meaning of the oath that is considered valid is the one understood by the person administering the oath.
