And Abu Sa`eed al-Khudri said, that the Messenger of Allah (S) said:
"Moses (AS) said: 'O Lord! Teach me something that I can remember You
with and I can supplicate You with'. He (Allah Ta'ala) said:'Say 'Laa
ilaaha ill Allah', O Musaa'. He (Musaa) said: 'Allof your servants say
this'. He (Allah) said: 'If the sevenHeavens and those who dwell in
them other than Me and the seven Earths are put into one pan (of the
scale) and 'Laa ilaaha illAllaah' is put into the other; 'Laa ilaaha
ill Allah' would be heavier.'" [Ibn Hibbaan and Haakim]
Laa ilaha il-Allah is the stuffof legends. It is the calling card of
the Eternal Prime Mover. It has rights over us.It's a contract, an
oath, a promise to love Allah before the people, fear Allah more than
the people, and to ask ourselves in every situation, "What does
Allahwant me to do here?" It's avow to trust Allah before the people,
call upon Allah in times of hardship, thank Allah in times of plenty,
and know in our bones that our return is to Him.
