Ubayy ibn Ka’b RadiAllahu Anhu se rivayat hai ki RasoolAllah sallallahu alaihi wa sallam ne farmaya: “Ye do Namazein (Fajar aur Isha) Munafiqo (Farebio) par bahut bhari hai, Agar tum jaan lete ki in do Namazon ka kitna Sawab hai to tum Ghutno ke bal chal kar bhi aatey.
[Sunan Abu Dawud, Vol 1, #552-Hasan]
Narrated Ubayy ibn Ka’b RadiAllahu Anhu The Apostle of Allah Mohammad Peace and Blessing be upon him said: “These Two Prayers (Fajar and Isha) are the ones which are most Burdensome to Hypocrites. If you knew what they Contain (i.e. blessings), you would come to them, even though you had to Crawl on your Knees.
