أبْشِرُوا وبَشِّرُوا مَنْ وَرَاءَكُمْ أنَّهُ مَنْ شَهِدَ أنْ لا إله إلاَّ الله صادِقاً بِها دَخَلَ الجَنَّةَ
It is reported that the Messenger of Allah, peace and blessings of Allah be upon him, said:
“Rejoice, and give glad tidings, to whoever testifies that there is no god worthy of worship except Allah, being sincere in this, will enter Paradise.” This hadith was transmitted by Ahmad (4/402, 411) and at-Tabarani in al-Mu’jam al-Kabir, according to Abu Musa, may Allah be pleased with him.
Also in al-Silsila al-sahiha (712).
