Hadrat Ali (Radi Allahu Ta’ala Anhu) narrated: when in the morning the sun was high in the sky as it is at the time of Asr Salaah (after noon), the Prophet used to say two Rakahs as lshraq Salaah and when it is as high in the sky in the east as it is in the west at the time of Zuhar Salaah, he would perform four Rakaats as Chasht Salaah. [Shamail -e- Tirmizi]
It is reported in a tradition that the Messenger of ALLAH said, If anyone sits in his place of Salaah when he finishes the Fajr Salaah till he performs the two Rakaats of lshraq Salaah, saying nothing but what is good, his sins will be forgiven him even if they are more than the foam of the sea. [Abu Dawud – Mishkat]
The majority of the Ulama hold that Chasht Salaah is mustahab (supererogatory). It should be said sometimes, and sometimes it should be omitted. It was the practice of the Prophet in regard to many nafil Salaah (i.e sometimes he said them and sometimes he did not). Majority of the companions of the Prophet and those who followed them also did likewise. The Ulama differ in the number of Rakaats for Chasht Salaah minimum number being two and maximum number being eight. The mashaikh have generally recited and recommended recitation of the surahs as Shams (XCI) ad – Du’a (XCIII) al – Lail (XCII) and al – lnshirah (XCVI). After finishing this Salaah, dua should be recited. One hundred – times recitation of this dua has been reported in some asar (traditions reported by the companions of the Prophet).
“O ALLAH! Forgive me and have mercy on me. Accept my repentance, for Thou art indeed the best acceptor of repentance and the most forgiving.” Nafil Salaah before Asr Salaah Hadrat Abdullah bin Umar (Radi Allahu Ta’ala Anhu) narrated that the Prophet said: ALLAH’s mercy be on the man who performs four rakahs (nafil) before Asr Salaah. [Tirmizi, Musnad Ahmad]
Awwabaeen Salaah after Maghrib Salaah
Hadrat Muhammad bin Ammar son of Hadrat Ammar bin Yasir (Radi Allahu Ta’ala Anhu) narrated that he saw his father reciting six rakahs after Magrib Salaah and heard him saying that he had seen the Prophet doing that and that the Prophet said: If any servant of ALLAH performs Salaah six rakahs after the Magrib Salaah his sins will be forgiven even if they are more than the foam of the sea. [Ma’rif -ul- Hadis, Mujim Tabaran]
Nawafil of Isha Salaah
It is better and commendable to perform four rak’ahs before the four fard rak’ahs of Isha Salaah. After the fard, two rak’ahs of sun nat – (I) Muakkadah should be said. If one is inclined, he may also perform two rakahs as nafl after that. The number of rakahs of sunnat is thus six. [Bahishti Zewar]
