The Mother of the Believers set an example of patience and she earned by that resounding success in the very first steps toward advancing the prophetic message. The Prophet (ﷺ) never heard anything detesting to him from rejected and belying that grieved him except that he was consoled by her.
When the Prophet (ﷺ) came out with his call in the open, the Quraish excommunicated Banu Hashim. The crisis came to a head and the effects of the banishment became fatal. Affairs degenerated between the message of Allāh’s Messenger (ﷺ) and the oppression of idolatry personified by the aristocrats of the Quraish. Their intellect became befuddled in their empty heads except for injustice, oppression and subjugation of the weak. Their idle minds shuddered except for corruption and idol worshipping. However, the Muslims exercised graceful patience.
Khadijah remained solidly behind the Messenger of Allāh (ﷺ), girding his loins and sharing with him in bearing the harm of his people with patience and equanimity in expectation of reward until Allāh implemented His Decree on this oppressive and persistent boycot which was fatal for the believers who were under siege.
When the siege ceased, At Tāhirah (Khadijah) came out triumphantly with the fruits of her patience, prosecuting with the Messenger of Allāh (ﷺ), her journey through life as a faithful wife.
Sayyidah Khadijah spent close to the quarter of a century under the shadow of Allāh’s Messenger (ﷺ). Throughout her stay with him, she discharged her obligation as a righteous wife to her husband. She shared with him his moments of joy, caring for his pleasures and happiness and devoted to what brings life to them.
It is clear from her generosity that when the people were afflicted with a period of drought after her marriage of Allāh’s Messenger (ﷺ), Sayyidah Halīmāh As-Sa’diyyah, foster mother of the Prophet (ﷺ) visited. She went back with the camels loaded with water and forty heads of goat from the wealth of Khadijah.
After she came out of the blockade, Khadijah lived for only a little while before she answered the call of her lord. Her pure soul soared to the heavens well-pleasing and well-pleased unto Allāh.
"She died three years before the hijrah and she was buried at Hajūn”
True is the statement of the one who said:
"If women were like the one we missed [Khadijah], women would have been given preference above men."
