Riyad as-Salihin, Book 2, Hadith 701 (In-Book) ⓘ
Mu'awiyah bin Al-Hakam As-Sulami (May Allah be pleased with him) reported: While I was in Salat with Messenger of Allah, a man in the congregation sneezed and I responded with: 'Yarhamuk-Allah (Allah have mercy on you).' The people stared at me with disapproving looks. So I said: "May my mother lose me. Why are you staring at me?" Thereupon, they began to strike their thighs with their hands. When I saw them urging to me to remain silent, I became angry but restrained myself. When Messenger of Allah concluded his Salat. I have never before seen an instructor who gave better instruction than he, may my father and mother be sacrificed for him. He neither remonstrated me, nor beat me, nor abused me. He simply said,"It is not permissible to talk during Salat because it consists of glorifying Allah, declaring His Greatness as well as recitation of the Qur'an," or he said words to that effect." I said: "O Allah's Messenger, I have but recently accepted Islam, and Allah has favoured us with Islam. There are still some people among us who go to consult soothsayers." He said, "Do not consult them." Then I said: "There are some of us who are guided by omens." He said, "These things which come to their minds. They should not be influenced by them."(Muslim).
وعن معاوية بن الحكم السلمي رضي الله عنه قال: "بينا أنا أصلي مع رسول الله صلى الله عليه وسلم ، إذا عطس رجل من القوم فقلت: يرحمك الله، فرماني القوم بأبصارهم ! فقلت: واثكل أمياه ! ما شأنكم تنظرون إلى؟ فجعلوا يضربون بأيديهم على أفخاذهم ! فلما رأيتهم يصمتونني لكنى سكت. فلما صلى رسول الله صلى الله عليه وسلم، فبأبي هو وأمي، ما رأيت معلما قبله ولا بعده أحسن تعليماً منه، فوالله ما كهرني ولا ضربني ولا شتمني، قال: "إن هذه الصلاة لا يصلح فيها شئ من كلام الناس، إنما هى التسبيح والتكبير، وقراءة القرآن" أو كما قال رسول الله صلى الله عليه وسلم قلت: يا رسول الله، إنى حديث عهد بجاهلية، وقد جاء الله بالإسلام، وإن منا رجالً يأتون الكهان؟ قال: "فلا تأتهم، قلت: ومنا رجال يتطيرون؟ قال: ذاك شئ يجدونه في صدورهم، فلا يصدهم" ((رواه مسلم)).
