The obligatory (obligatory) prayer of Esha is 4 rak'ats , which all Muslims have to recite. The obligatory part has to be performed with the congregation under the leadership of Imam, but if there is any difficulty, it can be read by oneself. However, if you read with Jamaat, it is twenty-seven times more reward. Before this there are 4 rak'at Sunnah prayers. This is optional prayer It is also encouraged to read and should be read if there is time , but not reading will not be a sin. It is obligatory to perform 2 rak'ats of Sunnah prayer after 4 rak'ats, which is an important Sunnah (Sunnah Muakkadah) and the Prophet never abandoned it during his lifetime. Then , some people perform 2 rak'ats of nafl prayers for which no document has been found. In fact , naafil prayers can be performed at any time of the day or night except during the forbidden time. It is not just a matter of reading 2 rak'ats . The next prayer is the Witr prayer, but the Asr prayer has nothing to do with it. It is better to wake up on the last night and recite Tahajjud after the prayer. However, for those who cannot wake up properly , it should be recited immediately after the Asr prayer. According to the hadith , Vitr prayers can be performed 1 rak'at , 3 rak'ats , 5 rak'ats , 8 rak'ats. Method of Witr Prayer: Ali says that the Prophet (peace and blessings of Allaah be upon him) said: Allaah is Vitr (odd). He loves the odd. Therefore , O bearers of the Quran! You perform the Witr prayer. - Tirmidhi , Abu Dawood , Nasai Sahabi Jabir said , the Prophet (peace and blessings of Allaah be upon him) said: Whoever fears that he will not be able to get up on the last night , let him perform the Witr prayer on the first night. And whoever thinks that he can get up on the last night , let him perform the Vitr prayer on the last night. That is why the angels attended the last night's prayer . And it's much better. - Sahih Muslim [There is disagreement among Muslims about the method of Witr prayer. Usually three rak'ats of Vitr prayer are offered. Dua Qunoot is read before or after the last rak'ah rukura] Dua Qunoot the اللهم انا نستعينك ونستغفرك ونؤمن بك ونتوكل عليك ونثنى عليك الخير ونشكرك ولا نكفرك ونخلع ونترك من يفجرك-اللهم اياك نعبد ولك نصلى ونسجد واليك نسعى ونحفد ونرجو رحمتك ونخشى عذابك انَّ عَذَابَكَ بِالْكُفَّارِ مُلْحِقٌ Pronunciation Allahumma inna nasta'unuka , wa nu ' minu biqa , wa natawakalu ' alaika , wa nushni ' alaiku khaira . Allahumma yaka na ' budu wa lakanusalli , wa nasjudu , wa ilaika nas ' a , wa nahfidu , wa narju rahmataka , wa nakhsha ajabaka , inna ajabaka bil kuffari mulhikk.
