The Shia believe that in the midst of this joined period, one can perform the 'Maghrib' as well as Isha prayer jointly without any interruption, however, the Sunnis say that: It ought to be recited from the beginning of sunset until the fading of the evening twilight that is exclusive for the 'Maghrib' prayer and 'Isha' should not be recited during this particular time; and from the time of the fading away of the evening twilight up to the legal midnight, is exclusive for the Isha prayer and one cannot perform the 'Maghrib' prayer during this particular time.

Result: According to the theory of the Shias, after the arrival of the legal noon, one can perform the noon prayer and immediately after performing the afternoon prayer or can delay the noon prayer till close to the beginning of the special time of the afternoon prayer such that he can finish the noon prayer before the specific time of the afternoon prayer and perform the afternoon prayer.

Thus, to jointly pray the noon and afternoon prayers is perfectly alright although it is recommended to perform the noon prayer after 'mid-day' and the after noon prayer when the shade of things turn out equal to their lengths.

One can also perform the 'Maghrib' prayer when the specific time of 'Maghrib' arrives, and immediately after that, can perform the Isha prayer, or delay the 'Maghrib' prayer till close to the specific time for the Isha prayer so as to terminate the 'Maghrib' prayer before the specific time for Isha prayers, then perform the Isha prayer and in this way, join the 'Maghrib' and Isha, although it is recommended to perform the 'Maghrib' prayer after the legal 'Maghrib' time and 'Isha' after the fading of the evening twilight from the western frontier.

This is the prospect that the Shias have. However, the Sunnis do not accept it as being permissible to pray the noon and afternoon prayers together or the 'Maghrib'and Isha for that matter, in the same manner, and at all times and places. Hence, the subject of discussion lies whether the joining of two prayers can be performed in the likely manner just as it is in 'Arafah' and 'Muzdalifah', or not.
