عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((الْكَلِمَةُ اللَّيِّنَةُ صَدَقَةٌ، وَكُلُّ خُطْوَةٍ يَمْشِيهَا إِلَى الصَّلَاةِ أَوْ قَالَ: إِلَى الْمَسْجِدِ صَدَقَةٌ))
Narrated by Sayyiduna Abu Huraira (may Allah be pleased with him), the Noble Prophet (peace and blessings be upon him) said: A gentle word is also charity, and a step taken towards prayer or the mosque is also charity. When a person walks on his feet to go, that too is charity.
