Responding to this, a great Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, said:
“When we study the life of the prophet (peace and blessings be upon him), we have to approach it from a holistic perspective. One ought to study how the Prophet (peace and blessings be upon him) received the revelation, undertook da`wah (preaching), his way in refining his companions’ souls, his care of all Muslims, and his outstanding qualities such as: trustworthiness, truthfulness, modesty, patience, generosity.
One also ought to study how the Prophet’s (peace and blessings be upon him) built the new Muslim state and Ummah and the afflictions he faced in this regard and his practicing acts of worship. For example, Allah Almighty obligated on him to pray as mentioned the Glorious Quran: “O you wrapped up in your clothes! stand at night ‘in prayer’ except a little -. ‘pray’ half the night, or a little less. Or add (a little) thereto – and recite the Qur’an in a measured way) (Al-Muzzammil: 1- 4). Such duty was obligated on him until he died (peace and blessings be upon him). Also, it has been reported that the Prophet (peace and blessings be upon him) used to fast most of Muharram, Rajab, Sha`ban, every Monday and Thursday from each week, and three days from each Hijri month (the 13th, 14th, and 15th).
Not only, the aspects of worship and manner, but one must also study the Prophet’s engagement in the public life. He used to spend time teaching Muslims, answering all their questions, taking care of their needs, and solving their problems. He also used to direct the armies, and many times he would participate with them, otherwise he would be following up on their news minute by minute. He also used to administer the Muslim nation in Medina, which requires vast amount of time and energy.
Furthermore, if we study the Prophet’s (peace and blessings be upon him) family life, we would learn about his mercifulness, forgiveness, affection towards family members, and how he used to participate in carrying out the daily chores of his household. We would also learn that the Prophet (peace and blessings be upon him) was married to one wife – Khadija (may Allah be pleased with her), who was older than him – until he (peace and blessings be upon him) reached fifty years-old. She lived with him during the times of difficulty and through the first days of receiving revelation, the great harm he faced along with his Companions and followers from the polytheists and pagans during the early stages of his call. They lived with him under siege – made by the polytheists – suffering from shortage of water and food supplies. It was only after the Prophet (peace and blessings be upon him) turned fifty-five years-old when he married more than one wife, and perhaps you are young now and do not know how it feels to be fifty-five. Allah Almighty describes this age as He says: “… then, after strength, appointed weakness and grey hair.” (Ar-Rum: 54)
However, what you have described as the “sex-life”, it is considered to be a part of the private life any man has with wife. Thus, detaching this aspect from the overall picture of the Prophet’s (peace and blessings be upon him) marital life – in order to study it separately – is actually similar to someone who sees a beautiful painting that has waterfalls, blue skies, and blossoming flowers and instead of enjoying the magnificent scenery, he chooses to look at a specific red or blue dot. As a result, one must gain overall knowledge of the Prophet’s family life from all angles, and encompass all its aspects before engaging in a precise subject.
With regards to Mariyah, she was given to the Prophet (peace and blessings be upon him) as a gift when he was almost sixty years-old. In addition, she was not a wife for him, she was rather a concubine. On the other hand, he used to stay each day with one of his wives. Therefore, what has been told to you that the Prophet (peace and blessings be upon him) used to stay with Mariyah every day is false. Besides, as far as we know Mariyah was not more beautiful than `A’ishah, Juwaireyah, Zainab, or Safiyyah. Thus, what you have been reading is an absolute delusion, and is not near to the truth.
Additionally, what has been mentioned in your question that the Prophet (peace and blessings be upon him) used to have an intimate relationship with all his wives in one night, this has not been the Prophet’s regular behavior. However, the Prophet (peace and blessings be upon him) did so once or twice, in order to clarify the permissibility of such action and other related sharia rulings could appear for the Muslim Ummah to learn.
Furthermore, we say that if Allah blessed someone with strength, would it be a flaw to be blessed with such a blessing? Rather, it is a flaw to be blessed with something and you misuse it, or use it correctly and do not thank Allah Almighty. It is important to mention here that after examining the Prophet’s life we realize how the Prophet (peace and blessings be upon him) is a human-being, who has reached perfection in all aspects of his humanity. By doing so, we will not call him as god or son of god as Christians call Jesus (peace and blessings be upon him).
Finally, after you study the life of the Prophet (peace and blessings be upon him) as whole, you will then be able to engage in studying any specific aspect of his life with a straight intellect and a correct ideology. So, you are advised to study the Prophet’s life from authentic and trustworthy sources in order to avoid misconceptions that have no basis or reality.”
