Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Qatadah bin Rabi’ (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah the Exalted has said: I have made five prayers obligatory upon your Ummah, and I have made it incumbent upon Myself that whoever guards these prayers at their appointed times, I will admit him to Paradise, and whoever does not guard them, then I have no covenant (of forgiveness) with him.”
