Nawafil upon entering the mosque

عَنْ أَبِىْ قَتَادَةَ السَّلَمِيِّ، أَنَّ رَسُوْلَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ

إِذَا دَخَلَ أَحَدُكُمُ الْمَسْجِدَ فَلْيَرْكَعْ رَكْعَتَيْنِ قَبْلَ أَنْ يَجْلِسَ

Hazrat Abu Qatadah al-Ansari^ra reported that Allah’s Messenger^sa said:

“If anyone of you enters a mosque, he should pray two rak’ahs before sitting down.”

(Sahih al-Bukhari, Kitab as-Salat, Hadith 444)
