Sayyidah Aishah al-Siddiqah (may Allah be pleased with her) narrates that she heard the Prophet (peace and blessings be upon him) say: "Indeed, Allah Almighty has made five prayers obligatory upon the servants in every day and night."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat from his teacher Muhammad bin Rashid; I do not know him. The narrator Rawwad bin al-Jarrah was declared "thiqah (trustworthy)" by Imam Ahmad, and Ibn Hibban also declared him "thiqah"; there is weakness in him. Hadiths about the obligation of prayer will come later, in the chapter on the travel prayer.
