مختصر صحيح بخاري
Mukhtasar Sahih Bukhari
Book of Tahajjud Prayer
Regularly praying two Sunnah rak‘ahs of Fajr; some call them voluntary.
Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says that the Prophet Muhammad (peace and blessings be upon him) did not observe any voluntary prayer as regularly as he observed the two rak'ahs (Sunnah) before Fajr.
