"Allah's Messenger was among the lightest of people in Salat with its completeness."
Jami` at-Tirmidhi Book 2, Hadith 89
← Previous Hadith the Prophet said: "When one of you leads the people in prayer then let him be brief, for indeed here are among them the young and the old, the weak and the ill. When one of you prays alone, then let him pray as he wishes."

Jami` at-Tirmidhi Book 2, Hadith 88 Next Hadith → Allah's Messenger said: "the key to Salat is the purification, its Tahrim is the Takbir, and its Tahlilis the Taslim, and there is no Salat for one who did not recite Al-Hamd and a Surah in the obligatory (prayer) or other prayers."
