• كُسَالَىٰ

Appears 2 times in the Quran.

1. 4:142 إِنَّ ٱلْمُنَٰفِقِينَ يُخَٰدِعُونَ ٱللَّهَ وَهُوَ خَٰدِعُهُمْ وَإِذَا قَامُوٓا۟ إِلَى ٱلصَّلَوٰةِ قَامُوا۟ كُسَالَىٰ يُرَآءُونَ ٱلنَّاسَ وَلَا يَذْكُرُونَ ٱللَّهَ إِلَّا قَلِيلًا

   Surely the hypocrites strive to deceive Allah, and He shall requite their deceit to them, and when they stand up to prayer they stand up sluggishly; they do it only to be seen of men and do not remember Allah save a little.
   

2. 9:54 وَمَا مَنَعَهُمْ أَن تُقْبَلَ مِنْهُمْ نَفَقَٰتُهُمْ إِلَّآ أَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَبِرَسُولِهِۦ وَلَا يَأْتُونَ ٱلصَّلَوٰةَ إِلَّا وَهُمْ كُسَالَىٰ وَلَا يُنفِقُونَ إِلَّا وَهُمْ كَٰرِهُونَ

   And nothing hinders their spendings being accepted from them, except that they disbelieve in Allah and in His Messenger and they do not come to prayer but while they are sluggish, and they do not spend but while they are unwilling.
