The Messenger of Allah ﷺ commanded us (to recite) when we sit in the middle of the prayer or at its end before the salutation: The adorations of the tongue, all good things, acts of worship, and the Kingdom are due to Allah. Then give salutation to the right side; then salute your reciter (i.e. the imam) and yourselves. Abu Dawud said: Sulaiman b. Musa hails from Kufah and he lives in Damascus. Abu Dawud said: This collection of traditions indicates that al-Hasan (al-Basri) heard traditions from Samurah (b. Jundub). (Using translation from Abū Dāʾūd 975)
"إذا كانَ في وسط الصَّلاةِ أوْ حين انْقضائها، فابْدءوا قبْل التَّسليم، فقُولوُا: التحيَّاتُ الطَّيِّباتُ والصلوَاتُ والسَّلامُ والملكُ لله، ثُمَّ على النَّبِيِّين، ثُمَّ سلِّموا على أقارِبِكُمْ وعلى أَنْفِسكُمْ".
