In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Salaah and Salaam Upon The Prophet:

Allaah [The Exalted] said:

إِنَّ ٱللَّهَ وَمَلَـٰٓٮِٕڪَتَهُ ۥ يُصَلُّونَ عَلَى ٱلنَّبِىِّۚ يَـٰٓأَيُّہَا ٱلَّذِينَ ءَامَنُواْ صَلُّواْ عَلَيۡهِ وَسَلِّمُواْ تَسۡلِيمًا

Allah sends His Salah on the Prophet (Muhammad) and also His angels too (do so). O you who believe! Send your Salah on him (Muhammad) and (you should) greet (salute) him with the Islamic way of greeting (salutation i.e. As-­Salamu ‘Alaikum). [Surah al-Ahzaab. Verse 56]

The Du’aa After A’dhaan

Imaam Al Bukhaari [may Allaah have mercy upon him] reported from Jaabir Bin Abdillaah [may Allaah be pleased with him] that the Messenger of Allaah [peace and blessings of Allaah be upon him] said, “Whoever after listening to the Adhaan says:

اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ، وَالصَّلَاةِ الْقَائِمَةِ، آتِ مُحَمَّداً الْوَسِيلَةَ وَالْفَضِيلَةَ، وَابْعَثْهُ مَقَاماً مَحْمُوداً الَّذِي وَعَدْتَهُ

O Allaah! Lord of this perfect call (i.e. this call regarding not to ascribe partners to You) and of the regular prayer which is going to be established!] Kindly give Muhammad Al-Waseelah (highest position in Paradise) and Al-Fadhilah (extra degree of honour) and raise him to Maqam Mahmud (a station of praise and glory, i.e. the honour of intercession on the Day of Resurrection) which You have promised him], then intercession for me will be permitted for him on the Day Resurrection].
