QURAN 33:56
Indeed, Allah confers blessing upon the Prophet, and His angels [ask Him to do so]. O you who have believed, ask [ Allah to confer] blessing upon him and ask [ Allah to grant him] peace.

PROPHET MUHAMMAD (ﷺ) said:
The stingy person is the one before whom I am mentioned, and he does not send Salat (Darood) upon me.

PROPHET MUHAMMAD (ﷺ) said:
1) May the man before whom I am mentioned - and he does not send Salat (Darood) upon me - be humiliated.
2) And may a man upon whom Ramdhaan enters and then passes, before he is forgiven, be humiliated.
3) And may a man whose parents reached old age in his presence, and they were not a cause for his entrance to Paradise, be humiliated.

PROPHET MUHAMMAD (ﷺ) said:
No group gather in a sitting in which they do not remember Allah, nor sent Salat (Darood) upon their Prophet, except it will be a source of remorse for them. If He wills, He will punish them, and if He wills, He will forgive them.

PROPHET MUHAMMAD (ﷺ) said:
Never does a person send his Salam (Darood) to me except that Allah returns my spirit to me that I may return the Salam to him.

PROPHET MUHAMMAD (ﷺ) said:
1) Do not make your houses into graves, and
2) Do not make my grave an 'Eid (a regular place of visitation), and
3) Send your Salat (darood) upon me, for your Salat (darood) will reach me wherever you might be.

Fadalah bin Ubaid narrated:
“While the Messenger of Allah (ﷺ) was seated, a man entered and performed Salat, and he said: ‘O Allah, forgive me, and have mercy upon me.’ The Messenger of Allah (ﷺ) said: ‘You have rushed, O praying person. When you perform Salat, and then sit, then praise Allah with what He is deserving of, and send Salat upon me (ﷺ), then call upon Him.’” He said: “Then another man performed Salat after that, so he praised Allah and sent Salat upon the Prophet (ﷺ). The Prophet (ﷺ) said to him: ‘O praying person! Supplicate, and you shall be answered.’”
