The Prophet ﷺ would take the pledge of allegiance from his Companions (may Allah be pleased with them) when they embraced Islam to verify their faith, and teach them the most important duties required of them after being guided to Islam. In this hadeeth, Jareer ibn ‘Abdullah(may Allah be pleased with him) narrated that he gave the pledge of allegiance and made a covenant with the Messenger of Allah ﷺ to proclaim that none is worthy of worship save Allah, Exalted is He, and that Muhammad ﷺ is the Messenger of Allah. The implication of the two testimonies of faith is that when a servant of Allah proclaims them, he acknowledges Tawheed, i.e., unique Oneness of Allah, Exalted is He, and that He alone is worthy of worship, and also declares his faith in the Prophet Muhammad ibn ‘Abdullahﷺ, confirming such beliefs by his heart, believing in their meanings, and acting upon their implications. These are the testimonies that truly benefit a person in the Hereafter, helping him win Paradise and be delivered from Hellfire. He (may Allah be pleased with him) also pledged allegiance to the Prophet ﷺ to observe the five obligatory prayers during the day and night, which are: Fajr, Dhuhr, ‘Asr, Maghrib, and ‘Ishaa’, at their respective specified times, while fulfilling their conditions, pillars, and duties. He (may Allah be pleased with him) also pledged allegiance to pay the Zakaah, which is an obligatory financial act of worship that is due on one’s Zakatable wealth that reaches the Nisaab (i.e., a specific amount set by the Laws of Islam) after the passage of a lunar year. In this case, the owner is required to pay 2.5 % of hissurplus wealth. This also applies to the Zakaah payable on the cattle, crops and agricultural produce, trade goods, and Rikaaz (i.e., buried treasures or minerals), each according to the specified Nisaab and time of payment set by the Laws of Islam. Paying the Zakaah to its eligible recipients is rewarded with having one’s wealth blessed and earning abundant rewards in the Hereafter. On the contrary, withholding Zakaah out of stinginess warrants serious consequences in this worldly life and the Hereafter. Zakaah is an act of worship that incorporates the fulfillment of the right Allah, Exalted is He, and the right of His servants; it is a religious obligation and one of the pillars of Islam, and it helps fulfill the needs of the needy and poor. He (may Allah be pleased with him) also pledged allegiance to the Prophet ﷺ to hear and obey the commands of Allah, Exalted is He, and His Messenger ﷺ, reflected in his compliance with the commands and avoidance of the prohibitions. He (may Allah be pleased with him) also pledged allegiance to the Prophet ﷺ to be sincere with his fellow Muslims, by striving to benefit them, doing them good, and warding off evil from them by means of sayings and deeds. The fact that the Prophet ﷺ particularly made mention of one’s fellow Muslims in this context is due to it being theprevalent case, otherwise, it is required of Muslims to embody sincerity in their interactions with non-Muslims as well, by inviting them to Islam, and offering them the correct opinion when they seek their advice. Jareer (may Allah be pleased with him) was singled out for pledging sincerity to his fellow Muslims, because he (may Allah be pleased with him) was the leader and chief of his people. He (may Allah be pleased with him) went to the Prophet ﷺ in 10 A.H., embraced Islam, and his people followed in his footsteps. Therefore, the Prophet ﷺ guided him to the importance of embodying sincerity toward his fellow Muslims, because he needed it the most. It is deduced from the hadith that a Muslim is required to be sincere with his fellow Muslims, by treating them nicely, and avoiding cunning, deceit, cheating and betrayal..
