Like scattered dust..

Got this in an email, subhan’Allaah.. May Allaah purify our hearts and rectify our affairs!

Thawban (may Allah be pleased with him) narrated that the Prophet (blessings and peace of Allah be upon him) said: “I certainly know people of my ummah who will come on the Day of Resurrection with good deeds like the mountains of Tihamah, but Allah will make them like scattered dust.” Thawban said: O Messenger of Allah, describe them to us and tell us more, so that we will not become of them unknowingly. He said: “They are your brothers and from your race, worshipping at night as you do, but they will be people who, when they are alone, transgress the sacred limits of Allah.” [Ibn Majah (4245)]

This is a sahih hadith; it was classified as such by al-Buwaysari in Misbaah al-Zujaajah (4/246) and al-Albani in Al-Sahihah. Al-Mundhiri said in al-Targhib wa’l-Tarheb (3/170): Its narrators are thiqat (trustworthy).

Ibn Hajar al-Haithami (may Allah have mercy on him) in al-Zawaajir (3/49) regarded it as pretending to be righteous outwardly and transgressing the sacred limits; even committing minor sins when one is alone is regarded as something major, and he quoted this hadeeth as evidence, and said: The one whose habit is to make a show of being good and concealing his evil ways causes more harm and misguidance to the Muslims, because he has no piety and no fear of Allah.
