1. Sayyidina Khadija bint Khuwaylid was indeed a renowned businesswoman of Makkah. She was highly respected and admired for her intelligence, wisdom, and successful trading ventures. Khadija possessed exceptional business acumen and was known for her integrity and trustworthiness, which earned her a prominent position in the business community of Makkah.

2. It is said that Khadija elegantly proposed to Hazrat Muhammad (SAW), expressing her admiration for his noble character and his reputation for honesty. Prior to her marriage to Muhammad, she had been married twice before, but both marriages ended in divorce. However, these previous marriages do not diminish her status as a remarkable woman.

3. At the age of 40, Khadija married Prophet Muhammad, who was 15 years younger than her. Their marriage was based on mutual respect, trust, and love. Despite the age difference, their relationship was strong and harmonious, with Khadija playing a vital role in supporting and encouraging Muhammad in his mission.

4. Khadija provided both financial and emotional support to Prophet Muhammad. She used her wealth to help fund his efforts and ensure the success of his mission. Her unwavering belief in him, even in the face of skepticism and opposition from others, served as a source of strength for Muhammad during the early years of Islam.

5. Not only was Khadija a pillar of support for Prophet Muhammad, but she was also the first person to embrace Islam. Her acceptance of the message of Islam set a powerful example for others to follow, and her conversion marked a significant milestone in the history of Islam.

6. Khadija accompanied Prophet Muhammad during a journey to At Shoaib ibn Abi Talib, providing him with companionship and moral support. Her presence during this journey demonstrated her unwavering commitment to the mission of Islam and her dedication to standing by Muhammad's side.

7. Tragically, Khadija and Muhammad did not have any sons who survived childhood. They had four daughters: Umm Kulthūm, Ruqayyah, Zaynab, and Fāṭimah. These daughters played important roles in the development of Islam and the continuation of Muhammad's legacy.

8. It is believed that Allah sent greetings to Khadija through Jibrael (the archangel Gabriel) and gave her glad tidings of a house in Jannah (Paradise). This divine recognition and honor bestowed upon her are a testament to her exceptional character and devotion to Islam.

9. Throughout her life, Khadija was given many honorifics to acknowledge her virtues and contributions. She was known as 'The Pious One' (Al Tahira) due to her impeccable moral character. She was also referred to as the 'Princess of Quraysh' (Ameerat-Quraysh) in recognition of her noble lineage and esteemed position within the tribe. Additionally, she was called 'Khadija the Great' (Khadija al-Kubra) to highlight her outstanding achievements and her immense impact on the early history of Islam.

10.  Khadija died in 'Ramadan of the year 10 after the Prophethood i.e., in November 619 CE. Muhammad later called this tenth year the 'Year of Sorrow', as his uncle and protector Abu Talib also died at this time. Khadija is said to have been about 65 years old at the time of her death. She was buried in Jannat al-Mu'alla cemetery, in Mecca, Saudi Arabia.

Another report from Muhammad bin Ishaq says that 'Abu Talib and Khadija bint Khuwaylid died in the same year. This was three years before the emigration of the Messenger of Allah (Muhammad) to Medina. Khadija was buried in al-Hajun. The Messenger of Allah buried her in her grave. She was 40 years old when the Messenger of Allah married her.

In the years immediately following Khadija's death, Muhammad faced persecution from opponents of his message and also from some who originally followed him but had now turned back. Hostile tribes ridiculed and stoned him. Muhammad migrated to Yathrib (Medina) after Khadija's death.

Prophet Muhammad himself spoke highly of Khadija, acknowledging her unwavering support and dedication. He said, “She believed in me when people disbelieved, she supported me with her wealth when people denied me their material aid, and Allah blessed me with children from her.” These words emphasize the profound love, respect, and gratitude that Muhammad held for his beloved wife.

In conclusion, Khadija bint Khuwaylid was a remarkable woman who made significant contributions to the early days of Islam. Her role as a successful businesswoman, her pivotal support of Prophet Muhammad, her conversion to Islam, and her unwavering dedication to the cause make her a revered figure in Islamic history. Khadija's legacy continues to inspire and serve as a powerful example of strength, resilience, and devotion for Muslims around the world.
