وَمَا مَنَعَهُمْ أَن تُقْبَلَ مِنْهُمْ نَفَقَٰتُهُمْ إِلَّآ أَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَبِرَسُولِهِۦ وَلَا يَأْتُونَ ٱلصَّلَوٰةَ إِلَّا وَهُمْ كُسَالَىٰ وَلَا يُنفِقُونَ إِلَّا وَهُمْ كَٰرِهُونَ
And naught preventeth that their contributions should be accepted from them save that they have disbelieved in Allah and in His messenger, and they come not to worship save as idlers, and pay not (their contribution) save reluctantly.

Chapter: Whoever dragged his Izar without conceit
Narrated Abu Bakra:
The solar eclipse occurred while we were sitting with the Prophet (ﷺ) He got up dragging his garment (on the ground) hurriedly till he reached the mosque The people turned (to the mosque) and he offered a two-rak`at prayer whereupon the eclipse was over and he traced us and said, "The sun and the moon are two signs among the signs of Allah, so if you see a thing like this (eclipse) then offer the prayer and invoke Allah till He remove that state."
