To clasp one's hands by interlocking the fingers in the mosque or outside the mosque
Sahih Bukhari
حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي بُرْدَةَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ جَدِّهِ، عَنْ أَبِي مُوسَى، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ الْمُؤْمِنَ لِلْمُؤْمِنِ كَالْبُنْيَانِ، يَشُدُّ بَعْضُهُ بَعْضًا ". وَشَبَّكَ أَصَابِعَهُ.
Narrated Abu Musa: The Prophet (ﷺ) said, "A faithful believer to a faithful believer is like the bricks of a wall, enforcing each other." While (saying that) the Prophet (ﷺ) clasped his hands, by interlacing his fingers.
