Jami` at-Tirmidhi Book 49, Hadith 29
"You consider the signs to be punishment, whereas we used to think of them as a blessing during the time of the Messenger of Allah (ﷺ). We used to eat food with the Prophet (ﷺ) and we would hear the food's Tasbih." He said: "And the Prophet (ﷺ) was brought a container, so he put his hand it in, and the water began to spring from between his fingers. So the Prophet (ﷺ) said: 'Hasten to the blessed Wudu and the blessing from the heavens' until all of had performed Wudu."
"The first of what the Messenger of Allah (ﷺ) initiated with of Prophethood, when Allah wanted to honor him and grant His mercy upon His creatures, was that he would not see anything (in a dream) except that it would occur like the break of dawn. So he continued upon that for as long as Allah willed for him to continue, and seclusion was made beloved to him, such that there was not anything more beloved to him than being alone."
that Al-Harith bin Hisham asked the Prophet (ﷺ): 'How does the Revelation come to you?' The Messenger of Allah (ﷺ) said: 'Sometimes it comes to me like the ringing of a bell and that is the hardest upon me, and sometimes the angel will appear to me like a man, and he will speak to me such that I understand what he says.'" 'Aishah said: "I saw the Messenger of Allah (ﷺ) while the Revelation was descending upon him on an extremely cold day. Then it ceased and his forehead was flooded with sweat."
