To make the Heart Tender (Ar-Riqaq)
Chapter: The adoption of a middle course, and the regularity of deeds
Narrated 'Alqama:
I asked `Aisha, mother of the believers, "O mother of the believers! How were the deeds of the Prophet? Did he use to do extra deeds of worship on special days?" She said, "No, but his deeds were regular and constant, and who among you is able to do what the Prophet (ﷺ) was able to do (i.e. in worshipping Allah)?"
