Mentioning benefits from Surat al-Asr, and refuting those who say there is no disagreement among Muslims regarding creed, with the definition of faith as an example

The Shaykh : ... Allah (Blessed and Exalted is He) said in Surat al-Asr, summarizing for us this methodology that Muslims must follow: returning to their religion with the correct understanding and acting upon it. On that day, the believers will rejoice in the victory of Allah. Allah (Mighty and Majestic) said: . Those who believed and did righteous deeds: these are two conditions for success, so that we do not become among the losers in this world before the Hereafter: faith and righteous deeds.

This faith in the unseen is a matter of disagreement: is it only firm belief, or is it accompanied by righteous deeds? There are two well-known school opinions: the Maturidiyyah and the Asha'irah. The Asha'irah hold the opinion of the people of hadith, as I mentioned earlier: faith is action and belief. The Maturidiyyah say it is belief only, and deeds are not included in it. This disagreement may seem simple on the surface, but it led to a long and broad disagreement. Wars arose between the disputants in the past...
