In the name of Allah, Most Gracious, Most Merciful.
Sahl bin Sa’d (MAPH) reported: The Prophet (SAWS) said to Ali (MAPH), “By Allah, if a single person is guided by Allah through you, it will be better for you than a whole lot of red camels.” (Al-Bukhari and Muslim)
Abu Hurairah (MAPH) reported: The Messenger of Allah (SAWS) said: “He who calls others to follow the Right Guidance will have a reward equal to the reward of those who follow him, without their reward being diminished in any respect on that account.” (Muslim)
Commentary: “Better for you than red camels” is an allegory for everything that is better than anything else. Red camels used to be precious in Arabia, and their reference here is to highlight the value of guidance. Thus, this Hadith brings into prominence the importance of calling people towards Allah. But before calling others to the path of Allah, one must himself know it, and for this purpose, the knowledge of the Quran and Hadith is essential because one cannot provide any guidance in this respect without this knowledge.
The second Hadith has glad tidings for those who learn knowledge of religion, teach it and impart it to others.
SAWS: May Allah exalt his mention and protect him from imperfection
MAPH: May Allah be pleased with him
