The first four Caliphs are the most trusted followers of the holy Prophet (SAW) who were elected by the majority vote of the holy Companions RA of the holy Prophet (SAW). For this they are called the Khulafai Rashideen.
Shria means the way of life for the Muslims. Its sources are: The Qur'an, the Hadith (The sayings of the holy Prophet -SAW, the practice of the Companions, and the Qiyas of the Muslim Scholars and the experts of Islamic Jurisprudence.
The Muslims offer prayer as Hazrat Jibraiel (AS) taught the holy Prophet (SAW) and he practised and taught his Companions (RAU). Our beloved Prophet (SAW) made two sajood.

The Sunni Muslims are officially called AHL_I_SUNNAT WAL JAMA"AT. They follow the teachings of holy Qur'an and the holy Prophet (SAW) and the holy Companions(May Allah Karim be pleased with them). They have the same beliefs and the same way of worship as the holy Prophet (SAW) taught and the holy Companions acted upon. They follow the jurisprudence of any One of the Four Imams-Imam Abu Hanifa, Imam Malik, Imam Ahmad bin Humbal, Imam Sfafie (May Allah be pleased with them).
The Sunnat is applied to the actions of the Holy Prophet (SAW) while Hadith is applied to the sayings of the holy Prophet (SAW)
The life of Holy Prophet (SAW) is a beacon of light for the Muslims. Unfortunately, they learn no lesson from the best example of the life of the holy Prophet (SAW).
The holy Prophet Hazrat Muhammad (SAW), all the other Prophets (May peace and blessings of Allah Almighty be upon them all), the first four Rashidoon Caliphs RA, the Companions RA of the holy Prophet (SAW), and all the Allah-fearing people are the holiest people according to the arrangement I have mentioned.
Hazrat Ali (RAU) was one of the most distinguished, most loved, most respected and most honored Companions of the holy Prophet (SAW). The youngest and most loved daughter of the holy Prophet (SAW) was married to him. He was also the cousin of the holy Prophet (SAW). His services to Islam are unmatchable. He was the Fourth Rightful Caliph of Islam. He is the spiritual guide in most of the Sufi Silasil. His miraculous deeds cant be enumerated in brief. Those need a book.
They should turn to the Sunna (the way the holy Prophet SAW behaved) or Hadith (the sayings of the holy Prophet SAW), or try to find it in the way the holy Companions f the beloved Prophet Hazrat Muhammad SAW acted, and then used the common intellect of the Muslim Scholars of Muslim Jurisprudence.
