The Holy Prophet (Sallallahu alaihi wa sallam) has emphasized about the Ahle Bait and the along with them Sahabah that Allah Ta’ala should be feared about them, as given in Jame’ Tirmidhi:
Translation of Hadith: It has been narrated on the authority of Hadhrat Abdullah bin Maghfal (May Allah Ta’ala be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: Fear Allah Ta’ala about My Sahabah. Fear Allah Ta’ala. Do not make them the target of your condemnation after Me. Whoever loves them, loves them out of love for Me. Whoever hates them, hates them out of his hate for Me. Whoever hurts them, hurts Me and whoever hurts Me, hurts Allah Ta’ala and whoever hurts Allah Ta'ala, He will hold him to account very soon.
The Holy Prophet (Sallallahu alaihi wa sallam) has declared relation with the Ahle Bait as a means of deliverance and as a means of safety from misguidance. Whoever attaches himself with them, will never be misguided. Then please consider, will those pure souls fall prey to chasing this material world?
Therefore on the occasion of the Hujjatul Wada'a, when the Holy Prophet (Sallallahu alaihi wa sallam) gave the whole world a message of peace, on the same occasion, He (Sallallahu alaihi wa sallam) also gave the order for attaching oneself with the Holy Quran and the Ahle Bait. Following them is a means of eternal blessings and is a strong guard against wrong beliefs and irreligiousness.
There is a Hadith in Sunan Baihaqi and in Jame’ Tirmidhi:
Translation of Hadith: It has been reported on the authority of Hadhrat Jabir (May Allah Ta’ala be well pleased with him): "I saw the Holy Prophet (Sallallahu alaihi wa sallam) on ‘Arafat. He (Sallallahu alaihi wa sallam) was on His she-camel, Qaswa and was giving a sermon. I heard Him saying, "O people, I leave with you 2 great ni'mah. Till you hold on to them, you will never be misguided. They are, the Book of Allah and My Ahle Bait.
When according to the Holy Prophet (Sallallahu alaihi wa sallam), the Ahle Bait save people from misguidance. Whoever attaches oneself with them cannot be on the wrong path, then is it correct to blame them with the love of this world (Hubb e Duniya), is it correct to label their struggle as a political struggle? Even after Allah Ta’ala declares their purity-
Allah intends only to remove all impurity of sins from you, O People of the House (of the Prophet, [even a doubt or trace of shortfall,]) and make you absolutely pure and clean by blessing you with (perfect) purity and wholesomeness. Surah Ahzaab (33:33)
When the Holy Prophet (Sallallahu alaihi wa sallam) prayed for them thus: "O Allah! These are My Ahle Bait. You remove from them and grant them absolute purity."
