The Prophet (SAWA) said, 'There is no need to stay awake at night except in three instances: when staying awake to recite the Qur'an, to gain knowledge, and for a bride to be offered to her husband.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): لا سَهَرَ إلّا في ثلاثٍ: مُتَهَجِّدٍ بالقرآنِ ، وفي طَلَبِ العِلمِ ، أو عَروسٍ تُهدى إلى زَوجِها.
