Bilāl the Abyssinian was a Companion of Prophet Muḥammad and Islam's first muezzin. His tomb—if we are to believe popular tradition—is located at Bāb aṣ-Ṣaġīr's ancient cemetery in Damascus, the alleged resting place of several holy men and women, including the first Umayyād Caliph Muʿāwīyā; Um Ḥabībā, daughter of Abu Sufīān and one of Muḥammad's numerous wives; Fāṭimā, the daughter of Imam Ḥusayn; etc. There exists, needless to say, no shortage of ancient mausoleums in and around Damascus; heck, I personally paid a visit to what passes for Abel's tomb many years ago.
Whether or not those graveyards host the remains they claim to, whether or not those men or women ever set foot in Damascus, and if they existed at all, is not the subject of this post. Various Muslim countries may dispute the honor of possessing the relics of this or that saint; the Wahhābis may reject necropolis wholesale and frown at tomb visitation; but the aura surrounding those people, their lives, and their achievements is seldom debated. Their biographies have meticulously been collected, “authenticated,” commented, and adopted by hundreds of millions of Muslims worldwide from time immemorial.
Bilāl was one of Islam's first martyrs (so were ʿAmmār ibn Yāsir and his ilk, but that's another story). Every Muslim knows how he eagerly adopted the Mohammedan faith when the believers were a tiny minority and how much he suffered for it. Bilāl was a slave of the cruel ʾUmayyā ibn H̱alaf, who was, along with Abu Ǧahl and Abu Lahab, one of Islam's deadliest enemies and a member of a powerful Qurayšite clan. The ruthless ʾUmayyā was hellbent on reclaiming his renegade slave to the old pagan faith, and towards that purpose, he'd put steadfast Bilāl to all kinds of torture, such as having the martyr lie down on burning desert sand with a heavy stone placed on his chest as to bring him to the verge of suffocation. Bilāl adamantly refused to renounce the one-and-only true faith, of course, and somehow survived the greatest ordeal of his life to the great relief of the Community of the Faithful. He went on to become Islam's first muezzin, and his beautiful voice is the stuff of legends.
The Forces of Darkness met their first defeat at the hands of the Muslims in the Battle of Badr. It was a day of reckoning for ʾUmayyā ibn H̱alaf, who was captured by ʿAbd ar-Raḥmān ibn ʿAwf, a companion of the Prophet Muḥammad and one of the ten to whom Paradise was promised. Bilāl sighted his old nemesis "the enemy of Allah" in shackles, helpless and defeated, and lost no time slaying him despite the vociferous protestations of ibn ʿAwf, who had pledged to spare ʾUmayyā's life.
Let's assume, for the sake of argument, that Bilāl and ʾUmayyā are indeed historical figures and that the above narrative is truthful—for the sake of this post, the veracity of the above narrative or the lack thereof is irrelevant since Muslims treat it as bona fide history of which they are proud—I find this anecdote particularly illuminating. The savage ʾUmayyā may have tortured Bilāl, but HE DID NOT KILL HIM when he could have easily done it with precisely zero accountability. On the contrary, it was Bilāl who needlessly butchered a captured ʾUmayyā who was no longer capable of hurting him or anyone; worse, he committed the deed despite the fact that his erstwhile tormentor was under the protection of another companion of the Prophet, just like himself.
To the Muslims, the martyr was Bilāl the executioner, not the victim he slew! This is almost as comical as the "martyrdom" of Basil al-ʾAsad, though in the latter case it was not about good versus evil, merely a tragic car accident transformed by obsequious media into an occasion to shed crocodile tears in order to curry favor with the ruler, just as their ancestors did under the French and before that the Ottomans.
Bilāl's was by no means a unique example. An even more egregious insult to common sense was the treatment the Muslims inflicted on the Jews of Medina, exiled, murdered, or enslaved to the last man and woman and yet perversely accused of “plotting” against the Muslim community in cahoots with “pagan” Qurayš. Even were this to be true, that is, that some of them did indeed conspire against Muḥammad, would that justify such a brutal and collective punishment? (Saʿd ibn Muʿāḏ notoriously advised Muhammad to kill Banū Qurayẓā's men and enslave the women and the children, and the Prophet concurred). Once again, one can't but marvel at the ease with which credulous Muslims have always accepted at face value that the Jews of Medina were the villains of the story and amply deserved their grim fate and much more.
There exists no shortage of such tales throughout history, of course, and they're by no means restricted to Christianity or Islam. There is one major difference, however: Assyrians, Greeks, Romans, Arabs, Mongols, Turks, and European powers may commit atrocities on a large—sometimes genocidal—scale, but criticizing them and denouncing their crimes is perfectly permissible. This is true particularly for events that are ancient history (many choose to refrain from condemning powerful nations or leaders who could silence and kill their opponents). It is legitimate to point to the massacres committed by, say, Alexander the Great in Tyre; exposing Genghis Khan for the mass murderer he was is perfectly alright; Hitler remains the ultimate impersonation of pure evil for many.
Highlighting misdeeds of prophets and their companions, objectively pointing to the crimes committed by organized religion, and subjecting pious criminals to the same scrutiny one does secular leaders are an altogether different story. Do that at your own risk and blame no one but yourself for the consequences.
As George Orwell would say, war is peace, freedom is slavery, and ignorance is strength. At least as far as monotheism and its bogus martyrs go.
