عَنْ سَهْلِ بْنِ سَعْدٍ سَمِعَ النَّبِیَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ لِعَلیٍّ رَضِیَ اللهُ عَنْہُ
فَوَاللهِ لأَنْ يَهْدِیَ اللہُ بِكَ رَجُلاً خَيْرٌ لَكَ مِنْ أَنْ يَكُوْنَ لَكَ حُمْرُ النَّعَمِ
Hazrat Sahl bin Saad, may Allah be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said to Ali, may Allah be pleased with him, “By Allah! If Allah helps you to guide a single person to the truth, it is better for you than [the most precious] red camels.”
(Sahih Muslim, Kitab al-Jihad wa al-Siyar)
