Regarding the opinion about the obligation of the solar eclipse prayer, Ibn al-Qayyim said…
It is upon the intelligent one to exert himself in performing voluntary acts of worship – so long as he is in a state of [good] health.
«…and if they knew what there is [of reward] in the ‘Ishaa and Fajr prayer, they would come to them even if they had to crawl»
Supplication is the weapon of the strong and the weak, and it is from the delights of the Prophets and the sincere, and with it they seek [aid from Allaah] to ward off all harm.
Missing the Fajr prayer and sleeping during its time instead of praying it, is from the greatest of the prohibited acts, and from the acts of the hypocrites.
We see some people when they need to break [away from] their prayer [short] for some emergency, or to join [the congregation when] the imaam [is about to start the prayer], or if they have invalidated their prayer – they do the tasleem. So is this act [of theirs] correct, or will the intention [to terminate the prayer] suffice?
