"O you who have believed, remember Allah with much remembrance" (Al-Ahzab: 41) means: with the tongue, and this is a remembrance that has no set time.
Yahya narrated from Khadash, from Maymun ibn 'Ajlan, from Maymun ibn Siyah, from Anas ibn Malik, who said: The Messenger of Allah (peace be upon him) said: "There is no group of people who gather to remember Allah, desiring by that nothing but His countenance, except that a caller from the heaven calls out to them: 'Rise, you are forgiven, for your bad deeds have been replaced with good deeds.'" From the hadith of Yahya ibn Muhammad.
﴿يَا أَيهَا الَّذين آمنو اذْكروا الله ذكرا كثيرا﴾ يَعْنِي: بِاللِّسَانِ، وَهَذَا ذِكْرٌ لَيْسَ فِيهِ وَقْتٌ.
يَحْيَى: عَنْ خَدَاشٍ، عَنْ مَيْمُونِ بْنِ عَجْلَانَ، عَنْ مَيْمُونِ بْنِ سِيَاهٍ، عَنْ أَنَسِ ابْن مَالِكٍ قَالَ: قَالَ رَسُولُ اللَّهِ عليه السلام: " مَا مِنْ قَوْمٍ اجْتَمَعُوا يَذْكُرُونَ اللَّهَ لَا يُرِيدُونَ بِذَلِكَ إِلَّا وَجْهَهُ، إِلَّا نَادَاهُمْ مُنَادٍ مِنَ السَّمَاءِ: قُومُوا مَغْفُورًا لَكُمْ، قَدْ بُدِّلَتْ سَيِّئَاتِكُمْ حَسَنَاتٍ ". مِنْ حَدِيثِ يحيى بن مُحَمَّد.
