Re: True sincerity from heart & Soul
It was narrated in The Musnad by Imam Ahmad that the Prophet (peace be upon him) narrated that he asked Jibreel, and then he asked Allah (majestic in His praise) about sincerity, and He answered,** “Sincerity is a secret of secrets I stored in the heart of the ones I love among My servants.” **
“Whoever works for Allah’s sake sincerely for forty days, the fountains of wisdom will flow from his heart to his mouth.” (Narrated by Ibn Adii and, from the same chain, Ibn Al-Jawziah in *Al-Mawdoat* through Abu Musa.)
