Ubaidullah bin Abi Rafi' عبيد الله بن أبي رافع · General Behavior (Kitab Al-Adab)

The Prophet (ﷺ) said: When you hear the barking of dogs and the braying of asses at night, seek refuge in Allah, for they see which you do not see.

The Prophet (ﷺ) said: When one of you comes to an assembly, he should give a salutation and if he feels inclined to get up, he should give a salutation, for the former is not more of a duty than the latter.
