Al-A'raf 7:26

Ya banee adama qad anzalnaAAalaykum libasan yuwaree saw-atikumwareeshan walibasu attaqwa thalikakhayrun thalika min ayati AllahilaAAallahum yaththakkaroon

O children of Adam, We have bestowed upon you clothing to conceal your private parts and as adornment. But the clothing of righteousness - that is best. That is from the signs of Allāh that perhaps they will remember.

O children of ’Ādam, We have sent down to you the dress that covers your shame and provides adornment. As for the dress of Taqwā (piety), that is the best. That is one of the signs of Allah, so that they may learn a lesson.
