Servants for the mosque
وَقَالَ ابْنُ عَبَّاسٍ: {نَذَرْتُ لَكَ مَا فِي بَطْنِي مُحَرَّرًا} لِلْمَسْجِدِ يَخْدُمُهُ.Ibn 'Abbas referred to the Verse: "... I have vowed to You what (the child that) is in my womb to be dedicated for Your services (free from all wordly work, to serve Your place of worship)..." (V.3:35)
Sahih Bukhari
حَدَّثَنَا أَحْمَدُ بْنُ وَاقِدٍ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ امْرَأَةً ـ أَوْ رَجُلاً ـ كَانَتْ تَقُمُّ الْمَسْجِدَ ـ وَلاَ أُرَاهُ إِلاَّ امْرَأَةً ـ فَذَكَرَ حَدِيثَ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ صَلَّى عَلَى قَبْرِهِ.
