One who performs the pilgrimage (Hajj) for the first time must shave the hair (halq) and not shorten it (taqseer). Since you did not deliberately contravene the ruling, then your pilgrimage is in order and you are not liable for Kaffara.
The Prophetâ€™s (peace be upon him and his progeny) marriage to Aisha is looked at by the enemies of Islam as a negative episode in the Prophetâ€™s life, using the current cultural view about the age of the wife. This cultural view about the success of the marriage and personal life of the wife when she marries at a later age is a result of our modern time and its complications, and did not exist during that time nor did it exist during later eras.
Anyhow, a researcher will see that history did not reflect that she was forced into the marriage. All this shows that what the enemies of Islam present as a negative side in the personality of the Prophet is not based on a realistic foundation. It is, rather, using an old incident that took place during totally different social circumstances and judging it based on a modern view of marriage.
Taqleed is an obligation based on intellect. Muslims are required to implement the laws of the Islamic religion, and they cannot be known in details and in a correct way except by referring to the people of expertise, who are the religious scholars and relying on them in their findings that they concluded by research and study. Evidence of this concept from the Holy Quran is when Almighty Allah said: “And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.”(Qur'an, 122:9).
