It is my pleasure to share with you the famous book "THE OVERWHELMING TRUTH" by the Grand Mufti of Oman (Sheikh Ahmed ibn Hamed Al-Khalili), the English translation).
In "The Overwhelming Truth (a discussion of some key concepts in Islamic theology)", Sheikh Ahmed refutes the accusations and suspicions of the malevolent people who have issued terrible judgments about the Ibadhis and dealt with them in an evil way. The book discusses three issues about. These are:
1) Their denial of seeing Allah;
2) Their opinion of the creation of the Qur'an;
3) Their belief in the permanent staying in the Fire of those who have committed the major sins (i.e. without repentance).
"…By Allah, the trails, tests, breakdowns and losses that this ummah suffers from today make it deserving of pity from its worst enemy, then how should we allow its suffering to be doubled and its wounds to be inflicted over again by these abuses, without pursuing it with refutation by convincing proof and evidence. That is why I have stood forward, in spite of many other preoccupations, to write this book in order explain the overwhelming proof of the truth, and to put an end to the suspicions of falsehood. Allah is Who makes truth as truth and declares the falsehood of the false. 'No, but We hurl the truth against falsehood and It breaks its head, and behold falsehood vanishes (al-Anbiya, 21.18)…"
