حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، أَنَّ أَبَاهُ الْقَاسِمَ، كَانَ يُصَلِّي قَبْلَ أَنْ يَغْدُوَ، إِلَى الْمُصَلَّى أَرْبَعَ رَكَعَاتٍ ‏.‏

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasimthat his father used to pray four rakas before he went to the place ofprayer. Translation Not Available
