How can Muslims keep themselves safe

A: If you see your Muslim brother committing a Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect), you should change this Munkar as much as you can. Do not pay attention to the discouraging ideas that come to your mind, such as the one mentioned in the question, as all this is inspired by Satan.As for the abstract of the book entitled Al-`Aqidah Al-Wasitiyyah you asked for, please find attached a copy thereof with the explanation of Shaykh Muhammad Khalil Al-Harras. It is a great `Aqidah (creed) which encompasses the beliefs of Ahl-ul-Sunnah wal-Jama`ah (adherents to the Sunnah and the Muslim mainstream). We recommend that you study it and teach it to others. As for the Tafsir (explanation of the meanings of the Qur'an) of the first five Ayahs of Surah Al-Kahf, we recommend that you read the Tafsir of Ibn Jarir and Ibn Kathir (may Allah be merciful with them), and that will be enough in shaa'-Allah (if Allah wills).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
