It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet of Allah (peace and blessings be upon him) said: "Be modest before Allah Almighty as He truly deserves." We said: "O Prophet of Allah, we (praise be to Allah) are modest." He (peace and blessings be upon him) said: "That is not what it means. Rather, whoever wishes to be modest before Allah as He truly deserves should guard the head and what it contains (the mind and senses), take care of the stomach and what it holds (of food and thoughts), and remember death and decay (in the grave). Whoever intends the Hereafter abandons the adornment of the world. So whoever does all this has truly been modest before Allah as He deserves." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A time will come upon the people when they will sit in circles in their mosques, but their only aim will be the world. Allah has no need of such people, so do not sit with them." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The Hour has drawn near, while people are only increasing in their greed for the world and only moving further away from Allah." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
