Mis‘ar bin Kidaam (rahimahullah) narrates:

Imaam Abu Hanifah (rahimahullah) had prepared a set of clothing that was more valuable than all his other clothing. This set comprised of a kurta, pants, shawl and turban, and its value was 1500 Dirhams or perhaps even more than that.

After performing the Esha Salaah, when all the people had retired to bed, Imaam Abu Hanifah (rahimahullah) would remove the clothing which he had worn during the day and would wear this extremely valuable set of clothing. After donning this set of clothing, he would apply ‘itr and thereafter stand in Salaah until the time of Fajr set in.
