It is narrated from Sayyiduna Abu Qatadah bin Rib'i (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty said: 'I have made five prayers obligatory upon you, and I have made a covenant with Myself that whoever guards them by offering them at their appointed times, I will (certainly) admit him into Paradise.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Imam al-Zuhri except Duwayd bin Nafi', and no one from Duwayd except Dubarah, and Baqiyyah is alone in narrating it."
