It was narrated that Abu Hurairah said: "The Messenger of Allah said: 'The most burdensome prayers for the hypocrites are the 'Isha' prayer and the Fajr prayer. If only they knew what (reward) there is in them, they would come to them even if they had to crawl'."
The lesson here is that we should strive to attend our daily prayers with sincerity and dedication in order to reap its rewards. We should also be mindful of our actions and words so that we can avoid hypocrisy which will prevent us from attaining Allah's blessings.
