Silsilat al-Ahadith al-Sahihah

The Noble Prophet (peace and blessings of Allah be upon him) said: "If, in the sight of Allah, the world had the value of even a mosquito's wing, He would not give a disbeliever a single sip of water from it." This hadith is narrated from several companions including Sayyiduna Sahl bin Sa'd, Sayyiduna Abu Hurairah, Sayyiduna Abdullah bin Umar, and Sayyiduna Abdullah bin Abbas (may Allah be pleased with them all), and it is also narrated mursal from Hasan and Amr bin Murrah.
