suyuti:2898a

"Four of their nights are like their days, and their days are like their nights; Allah fulfills his oath in these, frees progenies in these, and grants to a large number of people: ˹these are:˺ (1) the night of al-Qadr ˹in the month of Ramaḍān˺ and its morning, (2) the night of ʿArafah ˹in the month of Dhū al-Ḥijjah˺ and its morning, (3) the night of the middle of ˹the month of˺ Shaʿbān, [and (4) the night of ˹every˺ Friday and its morning.]

«أربعُ لَياليِهنَّ كأيامِهنَّ، وأيامُهنَّ كلَيالِيهن، يَبَرُّ الله فيهنَّ الْقَسم، ويُعتِقُ فيهنَّ النَّسم، ويُعطِى فيهنَّ الجزيلَ: (١) ليلةُ القدرِ وصباحُها، (٢) وليلةُ عرفة وَصَباحُها، (٣) وليلةُ النِّصفِ مِنْ شعبانَ وصباحُها، (٤ وليلةُ الجمعةِ وصباحُها)۔»
