عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ رِبَاطُ يَوْمٍ خَيْرٌ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ
It is narrated from Sayyiduna Abdullah bin Amr, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Guarding for one day is better than fasting and standing in prayer for a month.
