It is not from the Sunnah for people to sit together after the prayer in order to recite some remembrances (dhikr) or supplications (du’aa) – those that have been reported or those that have not been reported – by raising the voice and joining in unison. This act has become the normal custom in some lands, even to the point that this tradition has become accepted, by the people, as being one of the trademarks of the Religion. It is such that anyone who abandons it or forbids others from doing it is renounced, whereas renouncing that it be abandoned is what is truly evil.
The author of As-Sunan wal-Mubtadi’aat said: “Supplicating to Allah for forgiveness in congregation, in one unified voice, after finishing the prayer is an innovation. Likewise, their saying after the supplication: “O Most Merciful of those who show mercy, have mercy on us” (Yaa Arhamar-Raahimeen Arhamnaa) in congregation is an innovation. Connecting the optional prayer with the obligatory prayer without there being a period of division between the two is forbidden, as occurs in the hadeeth of Muslim. Reciting Al-Faatihahan extra time in honor of the Prophet is an innovation. The people’s gathering together, after the morning prayer is finished, in order to say: “O Allah, save me from the Hellfire” seven times is an innovation. Similarly, their adding after this: “… and from the torment of the Hellfire, by Your grace, O All-Mighty, O All-Forgiving” is an innovation.” 
Ash-Shaatibee (rahimahullah) said: “The Prophet (sallAllahu ‘alayhi wa sallam) did not used to say the supplication and the remembrances out loud immediately after prayer, all the time. Nor did he openly demonstrate doing it to the people, other than a time when it was done for the purpose of educating. This is because if he ha d done it and openly displayed it all of the time, it would have been from the Sunnah and the scholars would not have said that it is not from the Sunnah to do it, since its particularities, according to what they have stated, consist of its continuity and its being done out loud amidst the congregation of people. And it should not be said: ‘Had his supplication been done silently, it would not have been memorized from him’, for we will respond: ‘Whoever is accustomed to doing it silently, then it will definitely be exhibited from him, either because of its habit or because of his efforts to warn about its becoming obligatory.” 
This is as has been reported in Saheeh Al-Bukhari on Ibn ‘Abbaas that he (radyAllahu ‘anhu)) said: “Indeed, raising the voice whilst reciting dhikr, when the people would finish performing the congregational prayers, was done at the time of the Prophet (sallAllahu ‘alayhi wa sallam).” 
Imaam An-Nawawee (rahimahullah) said: “Ash-Shaafi’ee understood this hadeeth to mean that they would raise their voices with it for a short period of time, for the purpose of honoring the attribute of dhikr. It did not mean that they would say it out loud all the time. The best opinion is that the Imaam and the ones following him in prayer should recite the dhikrin low voices (after prayer), unless there is aneed to educate others (by saying it loudly).” 
Ibn Bataal said: “It is stated in Al-‘Utbiyyahthat Maalik (rahimahullah) considered that to be an innovation.” 
Ash-Shaatibee (rahimahullah) said: “It is concluded that making du’aain the form of congregation, all the time, was not from the actions of the Messenger of Allah rnor from his statements or silent approvals.” 
Ibn Al-Qayyim (rahimahullah) said: “As for making du’aa (supplication) after finishing the prayer, whether facing the Qiblah or facing the followers in prayer, then this was not from his (sallAllahu ‘alayhi wa sallam) guidance at all. Nor has this action been reported on him whether through a saheeh or hasan chain of narration. And as for specifying that to be done in the Fajr and ‘Asr prayers, then he never did this nor did any of his Khaleefahs. Nor did his ummah direct towards its implementation. Rather, it was s imply an opinion that was put into practice, by those that held that it was to take the place after the two prayers. And as for the supplications that are connected with the prayer, then indeed he (sallAllahu ‘alayhi wa sallam) used to say them while in his prayer and he commanded others to do that also. This is what is most befitting based on the condition of the one praying, for indeed when one prays, he is facing his Lord and conversing privately with Him, so long as he remains in prayer. But when he recites the tasleem, that private counsel comes to an end and his position of being in the presence of his Lord and his nearness to Him ceases. So how is it that he can abandon asking Him while he is in the state of private counsel with Him, nearness to Him and responsiveness, and then ask Him when he finishes from performing his prayer?! There is no doubt that the opposite of this condition is better for the one praying.” 
One should make Istighfaar (i.e. say Astaghfirullah) three times and then say the tasbeeh, the tahmeed, and the takbeer thirty three times each and then finish that with the tahleel, after the prayer. One should observe quietness in any state he is in after the prayer, such as standing, sitting or walking. And indeed, gathering to perform that (dhikr after prayer), participating in it and raising the voice out loud whilst doing it, are all innovations. The fact that it has become a habit seems insignificant to the people. And if anyone should call them to apply these similar characteristics to any other of the acts of worship, such as the prayer for entering the masjid (two raka’aat) for example, then they would renounce him, in the utmost manner. 
Also from its types is what has been innovated from making dhikr after each of the two Salaams at the end of the night prayer in Ramadaan, as well as doing it in a loud voice and in one unified rhythm. For indeed that is from the innovations.
