[Machine] I heard Al-Sa'ib bin Yazid Al-Kindi, the son of the daughter of Al-Namir, saying, "Prayer was initially prescribed as two units of prayer, then it was increased during the Salah of Al-Hadar (residing) and the prayer of Al-Safar (travel) was made shorter."

سَمِعْتُ السَّائِبَ بْنَ يَزِيدَ الْكِنْدِيَّ ابْنَ أُخْتِ النَّمِرِ يَقُولُ «فُرِضَتِ الصَّلَاةُ رَكْعَتَيْنِ رَكْعَتَيْنِ ثُمَّ زِيدَ فِي صَلَاةِ الْحَضَرِ وَأُقِرَّتْ صَلَاةُ السَّفَرِ»
