Dua after Azan, intercession of Prophet Mohammad (S.A.W.) becomes wajib

At the end of the Azan (athaan) recite Durood then
اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ وَالصَّلَاةِ الْقَائِمَةِ آتِ مُحَمَّدَاً الْوَسِيلَةَ وَالْفَضِيلَةَ وَابْعَثْهُ مَقَامَاً مَحْمُودَاً الَّذِي وَعَدْتَهُ إِنَّكَ لَا تُخْلِفُ الْمِيعَادَ

"O Allah, the Lord of this total call (invitation, proclamation) and the Lord of the Salat to begin, grant Muhammad 'intercession' ( a status) and grant him superiority and let him reach Mooqame Mahmood which You have promised, for definitely You do not go back on Your promises".
