“The Messenger of Allah (ﷺ) said when bowing and prostrating: ‘Subbuhun Quddusun Rabbul-mala’ikati war’ruh (Perfect, Most Holy, Lord of the Angels and the Spirit).”
“The Messenger of Allah (ﷺ) used to teach us the tashahhud just as he would teach us a surah of the Quran: ‘Bismillah, wa billahi. At-tahiyyatu lillahi wasalawatu wat-tayibaat, as-salamu ‘alaika ayah-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu ‘alaina a ‘ala ibad illahis-salihin, ashadu an la ilaha ill Allah, wa ashhadu anna Muhammadan ‘abduhu wa rasuluhu. As’al Allahal-jannah wa author billahi min an-nar (All compliments, prayers and pure words are due to Allah. Peace be upon you O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous slaves of Allah. I bear witness that that none has the right to be worshipped except Allah, and I bear witness that Muhammad is His slave and messenger. I ask Allah for Paradise and I seek refuge with Allah from the Fire.)'”
“We said: ‘O Messenger of Allah (ﷺ), we know how to send salams upon you, but how should we send salah upon you?’ He said: ‘Say: “Allahumma salli ‘ala Muhammadin ‘abdika wa rasulika kama salaita ‘ala Ibrahim wa barik ‘ala Muhammadin wa ‘ala ali Muhammadin kama barakta ‘ala Ibrahim (O Allah, send salah upon Muhammad, Your slave and Messenger , as You sent Salah upon Ibrahim, and send blessings upon Muhammad and upon the family of Muhammad as You sent blessings upon Ibrahim).”
The Messenger of Allah said: “The makers of these images will be punished on the Day of Resurrection, and it will be said to them: ‘Bring to life that which you have created.'”
The Messenger of Allah (ﷺ) used to setup a pulpit in the mosque for Hassan who would stand on it and satirise those who spoke against the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) would say: The spirit of holiness (i.e. Gabriel) is with Hassan so long as he speaks in defence of the Messenger of Allah (ﷺ).
