Jami` at-Tirmidhi Book 10, Hadith 66
"There are three times that the Messenger of Allah prohibited us from performing Salat in, burying our dead in: When the sun's rising appears until it has risen up; when the sun is at the zenith until it passes, and when the sun begins its setting, until it has set."
The Prophet said: "No one among the Muslim dies, and Salat is performed for him by a community of Muslims reaching one hundred, and they intercede (supplicate) for him, except that their intercession for him is accepted." In his narration, 'Ali bin Hujr said: "One hundred or more than that."
The Prophet said: "The rider is to be behind the funeral (procession), and the walker where he wishes, and the child should be prayed over."
