Jami` at-Tirmidhi Book 10, Hadith 112
The Messenger of Allah said: "Whoever consoles a bereaved mother, he will be clothes with a Burd in Paradise."
The Messenger of Allah said to him: "O Ali! Three are not to be delayed: Salat when it is due, the funeral when it is presented, and (marriage) for the single woman when someone compatible is found."
"The Messenger of Allah said, 'Allahu Akbar' over the deceased, so he raised his hands with the first Takbir, and he placed his right (hand) over his left."
