To make the Heart Tender (Ar-Riqaq)
81/17. Chapter:
How the Prophet (saws) and his Companions used to live
Sahih Bukhari
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، حَدَّثَنَا هِشَامٌ، أَخْبَرَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ يَأْتِي عَلَيْنَا الشَّهْرُ مَا نُوقِدُ فِيهِ نَارًا، إِنَّمَا هُوَ التَّمْرُ وَالْمَاءُ، إِلاَّ أَنْ نُؤْتَى بِاللُّحَيْمِ.
Narrated `Aisha: A complete month would pass by during which we would not make a fire (for cooking), and our food used to be only dates and water unless we were given a present of some meat.
