On the authority of Jabir (may Allaah be pleased with him)
who reported that he heard Allaah's Messenger (may peace be upon him) saying:
"The best way to celebrate the remembrance of Allaah is to say:
La ilaha illallah
"There is none worthy of worship except Allah. "
{Reported by Tirmidhi (hasan), Nasa'i, Ibn Majah, Ibn Hibban,
Bayhaqi in Shu`ab al-iman, from Jabir ibn `Abd Allah}
