And whenever we pray Night with Evening Prayers...
And whenever we pray Night with Evening Prayers, meaning at the start of the night or pray Evening Prayer with Night Prayer at the last time of midnight, we pray both the Prayers in their specific time, but it is Recommended to pray Evening Prayer at the start of the night and Night Prayer after the time of Zawal al-Shafaq (waning of evening twilight) and if a person does not do like this, it means that he has just not performed a recommended act. **Why it is allowed to pray two Prayers together?
** The proof regarding to pray two Prayers together is the traditions from Imam Jafar Sadiq (a.s.) that Shaykh al-Hurr al-Aamiliy has collected in his book.
We should also keep in mind that only Shia narrators have not only narrated traditions, but Sunni narrators have also narrated that it is allowed to pray two Prayers together (and that also if there is no legal excuse.) They have narrated from the Holy Prophet (a.s.) in their authentic books by Ibn Abbas, Muaath Ibn Jabal, Abdullah Ibn Masood and Abdullah Ibn Umar approximately ten traditions, all of which cannot be quoted in full but we just mention some of them: (1) The famous narrator of Sunni world, Ahmad bin Hanbal writes in his famous book Musnad from Ibn Abbas: The Holy Prophet (a.s.) used to pray Noon and Afternoon Prayers, and in the same way Evening and Night Prayers without the fear of enemy or without the excuse of travel.
(2) Then again he narrates this tradition from Jabir bin Zaid who narrated from Ibn Abbas that, I used to pray the Eight Rakahs of Noon and Afternoon Prayers or Seven Rakahs of Evening and Night Prayers together with the Holy Prophet (a.s.). And this tradition has been narrated by Ibn Abbas with different words. (3) Again he narrates from Abdullah Shaqiq: One day Ibn Abbas was delivering a sermon to the people and his speech was so long that the stars in the sky appeared.
A man from Bani Tamim tribe got up and objected to him that it was time for Evening Prayers and if the speech continues the time of Evening Prayers will pass away. Ibn Abbas told that person: I know much more about traditions and practice of the Holy Prophet (a.s.) than you. I have seen the Holy Prophet (a.s.) pray Noon and Afternoon Prayers together and Evening and Night Prayers together. The narrator says that I doubted about this and spoke to Abu Huraira who certified the saying of Ibn Abbas.
