Besides all of these proofs...

Besides all of these proofs, we have numerous ahadith that show that (prayers of Allah be upon him and his family) and the Infallible A'immah (peace be upon all of them) had access to the Knowledge of the Unseen.

Sometimes, they were given the knowledge of what would happen in the future such as the victory of Makkah, and the event surrounding Hatib ibn Abi Balta`ah, who wrote a letter to the people of Makkah which he gave to a woman named Sarah and she was to convey the letter to the polytheists of Makkah. She was close to being attacked by the Muslim army when she hid the letter under her long hair and continued on towards Makkah.

The Prophet (blessings of Allah be upon him and his progeny) ordered `Ali (peace be upon him) and a company of troops to go after her. The Prophet (blessings of Allah be upon him and his progeny) also informed the group of Muslims that when they reach to an area known as Rawdha al-Khak they will meet this woman, who has a letter from Hatib in her possession which is supposed to be given to the polytheists of Makkah.

The Prophet (blessings of Allah be upon him and his progeny) also commanded them to take the letter from her.

When the Muslim army found her, she initially denied having such a letter, however after repeated requests to her, she finally handed over the writing to `Ali (peace be upon him) and the group of Muslims.[^4] There are also events such as the prediction of the Battle of Mutah, and the martyrdom of Ja`far ibn Abi Talib (peace be upon him) and other soldiers and warriors in the Muslim army, which the Prophet (blessings of Allah be upon him and his progeny) told his followers while they were still in Madinah.[^5] Such examples in the life of the Holy Prophet (blessings of Allah be upon him and his progeny) are not small in number.

In Nahj al-Balagha, there are many forecasts to the events that would take place in the future, which show that Imam `Ali ibn Abi Talib (peace be upon him) also had access to this hidden knowledge.
