قُلْ إِن كُنتُمْ تُحِبُّونَ اللّهَ فَاتَّبِعُونِي يُحْبِبْكُمُ اللّهُ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ وَاللّهُ غَفُورٌ رَّحِيمٌ
Say (O Muhammad SAW to mankind): "If you (really) love Allah then follow me (i.e. accept Islamic Monotheism, follow the Quran and the Sunnah), Allah will love you and forgive you of your sins. And Allah is Oft-Forgiving, Most Merciful."
I heard the Prophet saying, "Ascribing false things to me is not like ascribing false things to anyone else. Whosoever tells a lie against me intentionally then surely let him occupy his seat in Hell-Fire." I heard the Prophet saying, "The deceased who is wailed over is tortured for that wailing."
