It is reported that we should send blessings upon him on many occasions, such as following the call to prayer, as in the Hadith recorded by Imam Ahmad from `Abdullah bin `Amr bin Al-`As, who said that he heard the Messenger of Allah say:

«إِذَا سَمِعْتُمْ مُؤَذِّنًا فَقُولُوا مِثْلَمَا يَقُولُ، ثُمَّ صَلُّوا عَلَيَّ، فَإِنَّهُ مَنْ صَلَّى عَلَيَّ صَلَّى اللهُ عَلَيْهِ بِهَا عَشْرًا، ثُمَّ سَلُوا اللهَ لِيَ الْوَسِيلَةَ، فَإِنَّهَا مَنْزِلَةٌ فِي الْجَنَّةِ لَا تَنْبَغِي إِلَّا لِعَبْدٍ مِنْ عِبَادِ اللهِ، وَأَرْجُو أَنْ أَكُونَ أَنَا هُوَ، فَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ عَلَيْهِ الشَّفَاعَة»

(When you hear the Mu'adhdhin, repeat what he says, then send Salah upon me, for whoever sends Salah upon me, Allah will send Salah upon him tenfold. Then ask Allah to grant me Al-Wasilah, which is a status in Paradise to which only one of the servants of Allah will be entitled, and I hope that I will be the one. Whoever asks Allah for Al-Wasilah for me, it will be permitted for me to intercede for him.) This was recorded by Muslim, Abu Dawud, At-Tirmidhi and An-Nasa'i. Other occasions when we should send Salah upon the Prophet include when entering or exiting the Masjid, because of the Hadith recorded by Imam Ahmad from Fatimah, the daughter of the Messenger of Allah who said: "When the Messenger of Allah entered the Masjid, he would send Salah and Salam upon Muhammad, and say,

«اللْهُمَّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ رَحْمَتِك»

(O Allah, forgive me my sins and open for me the gates of Your mercy) When he exited, he would send Salah and Salam upon Muhammad, and say,

«اللْهُمَّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ فَضْلِك»

(O Allah, forgive me my sins and open for me the gates of Your bounty.)'' We should also send Salah upon him during the Funeral prayer. The Sunnah is to recite Surat Al-Fatihah following the first Takbir, to send Salah upon the Prophet during the second Takbir, to make supplication for the deceased during the third Takbir, and in the fourth Takbir to say, "O Allah, do not deprive us of his reward, and do not test us after him.'' Ash-Shafi`i, may Allah have mercy on him, recorded that Abu Umamah bin Sahl bin Hunayf was told by one of the Companions of the Prophet that the Sunnah in the funeral prayer is for the Imam to pronounce the Takbir, then to recite Surat Al-Fatihah silently after the first Takbir, then to send Salah upon the Prophet then to offer sincere supplication for the deceased, but not to recite any Qur'an in any of the Takbirs, then to conclude by saying Salam silently. An-Nasa'i also recorded this from Abu Umamah, who said, "This is from the Sunnah,'' and he mentioned it. According to the correct view, such a statement reported from a Companion carries the ruling of Marfu`
