'Ali bin Abu Talib (May Allah be pleased with him)reported:
The Prophet (ﷺ) used to perform four Rak'ah before the 'Asr prayer, separating them with Taslim (i.e., offering blessings) on the favourite angels who are near Allah's proximity and the Muslims and the believers who come after them.[At- Tirmidhi].
