Saba 34:46

Qul innama aAAithukumbiwahidatin an taqoomoo lillahi mathna wafuradathumma tatafakkaroo ma bisahibikum min jinnatin inhuwa illa natheerun lakum bayna yaday AAathabinshadeed

Say, "I only advise you of one [thing] - that you stand for Allāh, [seeking truth] in pairs and individually, and then give thought." There is not in your companion any madness. He is only a warner to you before a severe punishment.

Say, “I advise you for one thing only: that you stand up before Allah, in pairs and in singles, then reflect; (you will easily appreciate that) there is no madness in your fellow (the Holy Prophet).” He is none but a warner to you in the face of a stern torment.
