Narrated 'Abdur-Rahman bin Abi Laila:
Ka'b bin 'Ujra met me and said,
"Shall I give you a present? Once the Prophet (صلى الله عليه و سلم) came to us and we said, 'O Allah's Apostle ! We know how to greet you; but how to send 'Salat'
upon you?
He (صلى الله عليه و سلم) said, 'Say:
Allaahumma Solli 'Alaa Muhammadin wa 'Alaa aali Muhammadin, kama Sol-laita 'Alaa aali ibraaheema innaka Hameedum Majeed.
Allaahumma barik 'Alaa Muhammadin wa 'Alaa aali Muhammadin, kama barakta 'Alaa aali ibraaheema,
innaka Hameedum Majeed."
(Bukhari Book #75, Hadith #368) (Muslim Book #004, Hadith #0804)


DUROOD FOR 1000 DAYS REWARDS

Hazrat Abdullah ibn Abbas (RA), a companion of the Holy Prophet (صلى الله عليه و سلم), says that Sayyiduna Rasoolullaah (صلى الله عليه و سلم) said that if a man recites the following Durood Shareef once, then for the coming 1 000 days the Angels of Allaah ta'AAla will be busy in writing reward for the reciter of this Durood:

جَزَى اللهُ عَنَّا مُحَمَّدًا مَّا هُوَ أَهْلُهُ
Jazallaahu 'Annaa (sayyidinaa wa mowlaanaa) muHammadan (Sollalaahu 'Alayhi wa sallam) maa huwa ahluhuu.

O Allaah! Give reward to our Hazrat MuHammad (Sollallaahu 'Alayhi wa sallam) the reward which is benefitting as he deserves".
