Best Deed: To offer Prayer at its appointed time
It is narrated on the authority of Jabir (Radi Allah Anhu) that he heard the Apostle (may peace and blessings be upon him) saying
"Verily between man and between polytheism and unbelief is the negligence of prayer."
[Sahih Muslim : Book 1 Kitab Al-Iman, Number 146]
