Shaykh Ahmad Saawi عَـلَيْهِ رَحۡمَةُ الـلّٰـهِ الۡـهَادِی reports from some saints of Islam that the one reciting this Salat upon the Prophet once receives the reward of reciting Durood 600,000 times. (Afdal-us-Salawat ‘ala Sayyid-is-Sadat, pp. 149)

5. Nearness to the Distinguished Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم

اَللّٰھُمَّ  صَلِّ  عَلٰی  مُحَمَّدٍ  کَمَا   تُحِبُّ  وَ  تَرضٰی  لَہٗ

One day somebody came [to the blessed court of the Beloved and Blessed Rasool صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم], and the Noble Rasool صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم made him sit in between himself and Sayyiduna Abu Bakr Siddeeq رَضِىَ اللهُ عَـنْهُ. The respected companions رَضِىَ اللّٰهُ عَـنْهُم were surprised as to who that honoured person was. When he had left, the Beloved Rasool صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, ‘When he recites Salat upon me, he does so in these words.’ (Al-Qaul-ul-Badi’, pp. 125)

6. Salat upon the Prophet to attain intercession

اَللّٰہُمَّ  صَلِّ  عَلٰی  مُحَمَّدٍ  وَّ  اَنْزِلْہُ  الْمَقْعَدَ الْمُقَرَّبَ  عِنْدَكَ  یَوْمَ الْقِیَامَۃِ

The Greatest Rasool صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated: The one who recites this Salat upon me, my intercession will become Wajib for him.

(Attargheeb Wattarheeb, vol. 2, pp. 329, Hadees 31)

1. Good deeds for 1000 days

جَزَی  اللّٰہُ  عَنَّا  مُحَمَّدًا  مَا  ھُوَ  اَھْلُہٗ

It is narrated by Sayyiduna Ibn-e- ‘Abbas رَضِىَ اللهُ عَنْهُمَا that the Noble Rasool صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated, ‘For the reciter of above supplication, seventy angels write good deeds (in his account) for 1000 days.’

(Majma’-uz-Zawaid, pp. 254, vol. 10, Hadees 17305)
