Benefit: The Permissibility of Joining Between More Than One Intention in a Single Supererogatory Prayer
In the Name of Allāh, the Ever Merciful, the Bestower of Mercy
Likewise, one is able to comibne the Sunnah prayer for making ablution or even the istikhārah prayer and other than them from the [nawāfil] prayers alongside one’s intentions [to pray the Rātibah and sunnah prayer of entering the masjid].
Translator's note: We understand from this that it is permissible to have more than one intention while carrying out a single Nāfilah prayer (i.e two units of prayer). We learn from this that we can pray two rakʿahs while having the intention of the Sunnah of Ẓuhr, Sunnah of ablution, Sunnah of entering the masjid and even the prayer of istikhārah.
