وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: «اِسْتَفْرِهُوا ضَحَايَاكُمْ فَإِنَّهَا مَطَايَاكُمْ عَلَى اَلصِّرَاطِ ».
The Messenger of Allah سبحانه وتعالى, peace and blessings be upon him and his family, said: "Choose the best of your sacrifices, for they are your mounts on the Sirat (Bridge)."
