Prayer is the pillar of Islam, so the Prophet ﷺ taught us the way to perform it and its supplications, including the words of at-tashahhud. In this hadith, Abdullah bin Abbas narrated that the Prophet ﷺ was keen to teach and encouraged his companions to memorize at-Tashahhud, as he did with the Quran. Its first sentence is to say, “All blessed services” which means dominion and greatness. “Prayers” is the supplication, the five daily prayers, or mercy. “The good deeds” are the righteous deeds that a servant dedicates to Allah only or those words he says to praise Him. “Greeting (peace), mercy, and blessings of Allah are upon you, O Prophet ﷺ. Greeting (peace) is upon us and upon the upright servants of Allah” means to greet the Prophet ﷺ and all righteous servants. By the way, Peace is one of Allah’s names which has two meanings: (1) Seeking Allah’s refuge and protection and (2) Negating any defects that people may attribute to Allah. The Prophet ﷺ taught them to particularly greet him, out of honor and high prestige, great themselves, and generally greet all the righteous. The righteous are those fulfilling Allah’s and his servants’ rights. Then, he completed the at-tashahhud by saying, “I bear witness that there is no god but Allah,” and added, as narrated by Ibn Omar in Sunan Abu Daoud, “alone without a partner of Him.” It means that a Muslim acknowledges and approves that there is no god worthy of worship except Allah, the Almighty. His saying, “And I bear witness that Muhammad is Allah’s Messenger,” means that a Muslim believes that Muhammad is the Messenger that Allah sent. He is not a liar, magician, or fortune teller, as the infidels say. Thus, a Muslim approves the Prophet’s message in every prayer. The other part of at-tashahhud is to exalt the Prophet’s mention. In the Two Sahihs, Ka’b ibn ‘Ujra narrated that the companions asked the Prophet ﷺ, “O Allah’s Messenger ﷺ, we learned how to greet you, so how we exalt your mention?” He said, “Say, ‘O Allah, exalt Muhammad’s mention and the family of Muhammad as You exalted the mention of Ibrahim’s family. You are the Praiseworthy and the Glorious. O Allah, bless Muhammad ﷺ and the family of Muhammad ﷺ as You blessed the family of Ibrahim. You are the Praiseworthy and the Glorious..
