Given the keenness of the Companions (may Allah be pleased with them) on performing acts of obedience and what brought them closer to earning the pleasure of Allah, Exalted is He, they (may Allah be pleased with them) often asked the Prophet ﷺ about the best good deeds that would bring them closer to Allah, Exalted is He. The answers of the Prophet ﷺ differed according to the different characters and situations of the inquirers, and what was more beneficial to them. In this hadeeth, Aboo Dharr Jundub ibn Junaadah Al-Ghifaaree (may Allah be pleased with him) asked the Prophet ﷺ, “What is the best deed?” He (may Allah be pleased with him) was asking about the most rewardable and beneficial good deeds, and the Prophet ﷺ replied with the most fundamental of all good deeds, namely, the belief in Allah, Exalted is He. Such belief means the decisive affirmation, absolute recognition, and full confession of the existence of Allah, Exalted is He, His Lordship, Divinity, Names and Attributes, and the fact that none but Him is worthy of worship, and the acceptance of all that the Prophet ﷺ told about his Lord, and the religion of Islam. Such belief is the best of all good deeds, and the greatest in the sight of Allah, Exalted is He, in terms of reward, because it is a precondition for the validity of all acts of worship, including: prayer, Zakaah, fasting, and others. He ﷺ then made mention of Jihaad, which is striving and fighting in the Cause of Allah to uphold His word, only for His sake rather than any other purpose. Jihaad is the best good deed, second to the belief in Allah, Exalted is He, and His Messenger ﷺ because it involves sacrificing one’s life for the sake of Allah, Exalted is He. Aboo Dharr (may Allah be pleased with him) then asked, "What is the best kind of manumission (of slaves)?" He (may Allah be pleased with him) wanted to know the best (most rewardable) manumission of slaves, and he ﷺ replied, "The manumission of the most expensive slave and the most beloved by his master," meaning the slaves whose prices are the highest and who are the most valuable and beloved to their owners. Aboo Dharr (may Allah be pleased with him) said, "If I cannot afford to do that, what should I do?" He (may Allah be pleased with him) asked the Prophet ﷺ about any other ways to earn such great rewards if he could not afford the manumission of slaves. He ﷺ replied, "Help an artisan or do good for an unskilled laborer,” meaning to help an artisan do his work or do good for an unskilled laborer who has not mastered his craft. AbooDharr (may Allah be pleased with him) asked, "If I cannot do that, what should I do?" He ﷺ informed him of a simple act of which no one is incapable, namely to refrain from harming others. The least thing a Muslim is required to do is to abstain from harming others, to ensure his own safety and that of others. He ﷺ said, "Refrain from harming others, for this will be regarded as a charitable deed for your own good.” The hadeeth highlights the diversity and abundance of good deeds that a Muslim may perform. It is also deduced from the hadeeth that the best (and most rewardable) good deed ever is having a sound belief in Allah, Exalted is He. It is inferred therefrom that the reward of an action is related to its benefit..
