Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Caution is of no avail against the decree, and supplication benefits as long as the decree has not descended. Affliction and supplication meet between the heaven and the earth and then wrestle with each other until the Day of Resurrection."
Al-Bazzar recorded it; its chain contains Ibrahim bin Khuthaym, who is matruk (abandoned).
