Hadith Takhrij« سنن ابن ماجہ/إقامة الصلاة 30 (922)، (تحفة الأشراف: 4597) (ضعیف) » (اس کے روای سعید شامی ضعیف ہیں اور قتادہ اور حسن بصری مدلس ہیں نیز: حسن بصری کا سمرة سے حدیث عقیقہ کے سوا سماع ثابت نہیں )
1001. Commentary: Reply to the Imam’s Salam. This means that when turning for salam (salutation of peace) at the end of the prayer, the followers (muqtadis) should intend to reply to the salam of the Imam. However, this narration is weak in its chain of transmission, and thus no ruling can be established from it. Nevertheless, the subsequent part of the narration, which commands mutual love and greeting one another with salam, is correct, because both of these matters are established from authentic ahadith.

´It was narrated that Samurah bin Jundab said:` “The Messenger of Allah (ﷺ) commanded us to greet our Imam with Salam, and to greet one another with Salam.”

Benefit: Both of these narrations are weak. Therefore, the ruling regarding replying (to sneezing) is not established from them.
