﴿ تَتَجَافَىٰ جُنُوبُهُمْ عَنِ ٱلْمَضَاجِعِ يَدْعُونَ رَبَّهُمْ خَوْفًۭا وَطَمَعًۭا وَمِمَّا رَزَقْنَٰهُمْ يُنفِقُونَ ﴾

“[and] who are im­pelled to rise from their beds [at night] to call out to their Sustainer in fear and hope; and who spend on others out of what We provide for them as sus­tenance.”

Their sides withdraw they rise from their lying places the places for lying down to sleep together with the bedding in order to spend the night in prayer tahajjud to supplicate to their Lord in fear of His punishment and in hope of His mercy and they expend of what We have provided them they give voluntary alms.
