Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The closest a servant is to his Lord is when he is in prostration."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and Imam al-Bazzar recorded it; its chain contains Marwan bin Salim, who is da'if (weak) and munkar al-hadith (his narrations are denounced).
