Narrated Mu'adh bin Jabal (RA): The Prophet ( صلی اللہ علیہ وسلم ) said: "Allah gave (a favor) as Sadaqah to you a third of your property, when you are about to die, as an increase in your good deeds." [Reported by ad-Daraqutni] . Ahmad and al-Bazzar reported the aforesaid narration from the Hadith of Abu ad-Darda. While Ibn Majah reported it from the Hadith of Abu Hurairah (RA). All of them (i.e. these three chains of narrators) are weak. However, they may strengthen one another (becoming Hasan), and Allah Knows Best.
