Up to her death in A.D. 619 (after a wedded life of five and twenty years) she was always ready with sympathy, consolation and encouragement whenever he suffered from the persecution of his enemies or was tortured by doubts and misgivings. “So Khadījah believed,” says the biographer of the Prophet, “and attested the truth of that which came to him from God and aided him in his undertaking. Thus was the Lord minded to lighten the burden of His Prophet; for whenever he heard anything that grieved him touching his rejection by the people, he would return to her and God would comfort him through her, for she reassured him and lightened his burden and declared her trust in him and made it easy for him to bear the scorn of men.” [17] Among the earliest believers were his adopted children Zayd and ʻAlī, and his bosom friend Abū Bakr, of whom Muḥammad would often say in after years, “I never invited any to the faith who displayed not hesitation, perplexity and vacillation—excepting only Abū Bakr; who when I told him of Islam tarried not, neither was perplexed.” He was a wealthy merchant, much respected by his fellow citizens for the integrity of his character and for his intelligence and ability. After his conversion he expended the greater part of his fortune on the purchase of Muslim slaves who were persecuted by their masters on account of their adherence to the teaching of Muḥammad. Through his influence, to a great extent, five of the earliest converts were added to the number of believers, Saʻd b. Abī Waqqāṣ, the future conqueror of the Persians; al-Zubayr b. al-ʻAwwām, a relative both of the Prophet and his wife; Ṭalḥah, famous as a warrior in after days; a wealthy merchant ʻAbd al-Raḥmān b. ʻAwf, and ʻUthmān, the third Khalīfah. The last was early exposed to persecution; his uncle seized and bound him, saying, “Dost thou prefer a new religion to that of thy fathers? I swear I will not loose thee until thou givest up this new faith thou art following after.” To which ʻUthmān replied, “By the Lord, I will never abandon it!” Whereupon his uncle, seeing the firmness of his attachment to his faith, released him. With other additions, particularly from among slaves and poor persons, the Prophet succeeded in collecting round him a little band of followers during the first three years of his mission. Encouraged by the success of these private efforts, Muḥammad determined on more active measures and began to preach in public. He called his kinsmen together and invited them to embrace the new faith. “No Arab,” he urged, “has offered to his nation more precious advantages than those I bring you. I offer you happiness in this world and in the life to come. Who among you will aid me in this task?” All were silent. Only ʻAlī, with boyish enthusiasm, cried out, “Prophet of God, I will aid thee.” At this the company broke up with derisive laughter.
