因此,真主保全了《古兰经》,使其不致因诵背者殉道而最初散失:真主引导正统的哈里发,并经先知的同伴们(愿真主赐福他并赐他平安,愿真主喜悦他们)一致认可,将《古兰经》的诸"阿亚"(迹象、奇迹、"节文")汇编成一册。在此之前,这些经文散见于各种材料的书写之中,也存于众多虔诚信士的记忆之中。真主又保护它免受其敌人的篡改:不信者、异端分子和伪先知无法歪曲它,因为真主使数以百万计的信士能够轻松地将其背诵于心。真主还保护了它的教义:他使成千上万的学者从其深邃的宝藏中学习,并将其传授给大众;他又在每个世纪之初派遣复兴宗教者。
同样,真主也保全了圣训(逊奈),使同伴及其后的世代(愿真主喜悦他们)能够记诵、笔录并传述先知(愿真主赐福他并赐他平安)的言论和他的道路的描述,并使他们得以延续践行逊奈的福分。后来,圣训知识的纯洁面临威胁,真主便使穆斯林民族涌现出记忆力超群、分析能力卓越的杰出人物。他们不知疲倦地奔走,搜集了数十万条圣训,并将先知(愿真主赐福他并赐他平安)那珍贵智慧的真实言辞,与那些因记忆薄弱而讹误的言辞、与那些无良骗子伪造的言辞,以及与众多学者、同伴及其追随者的言论区分开来。这些学者曾在各地的学术中心施教,并协助传承穆罕默德(愿真主赐福他并赐他平安)的遗产。所有这些成就,都依靠对所传述之词的精确留意,以及对数以千计的圣训传述者生平的详尽熟悉。 行动是保存教导的最佳方式，因此伊斯兰的复兴者们也恢复了对真实可靠的圣训的实践。然而不幸的是，仍有言论被归于先知（愿真主赐福他并使他平安）名下，而引述者可能并不知道圣训学者对这些圣训所作的裁定，因此讽刺的是，他们自己反而有违背先知关于将不实或不可靠之言归于他的广为流传的严厉警告的危险。例如，以下这些非常常见被引用的圣训，其真实性的程度实际上差异极大，它们来自先知（愿真主赐福他并使他平安）。
Hence, Allah preserved the Qur'an from being initially lost by the martyrdom of its memorisers, by guiding the Rightly-Guided Caliphs, endorsed by the consensus of the Messenger's Companions (may Allah bless him and grant him peace and may He be pleased with them), to compile the ayat (signs, miracles, "verses") of the Qur'an into one volume, after these had been scattered in writing on various materials and in memory amongst many faithful hearts. He safeguarded it from corruption by its enemies: disbelievers, heretics, and false prophets, by enabling millions of believers to commit it to memory with ease. He protected its teachings by causing thousands of people of knowledge to learn from its deep treasures and convey them to the masses, and by sending renewers of His Deen at the beginning of every century. Similarly, Allah preserved the Sunnah by enabling the Companions and those after them (may Allah be pleased with them) to memorise, write down and pass on the statements of the Messenger (may Allah bless him and grant him peace) and the descriptions of his Way, as well as to continue the blessings of practising the Sunnah. Later, as the purity of the knowledge of the Sunnah became threatened, Allah caused the Muslim nation to produce outstanding individuals of incredible memory-skills and analytical expertise, who journeyed tirelessly to collect hundreds of thousands of narrations and distinguish the true words of precious wisdom of their Messenger (may Allah bless him and grant him peace) from those corrupted by weak memories, from forgeries by unscrupulous liars, and from the statements of the enormous number of 'ulama', the Companions and those who followed their way, who had taught in various centres of learning and helped to transmit the legacy of Muhammad (may Allah bless him and grant him peace) - all of this achieved through precise attention to the words narrated and detailed familiarity with the biographies of the thousands of reporters of Hadith. Action being the best way to preserve teachings, the renewers of Islam also revived the practice of the blessed authentic Sunnah. Unfortunately however, statements will continue to be attributed to the Prophet (may Allah bless him and grant him peace) although the person quoting them may have no idea what the people of knowledge of Hadith have ruled regarding those ahadith, thus ironically being in danger of contravening the Prophet's widely-narrated stern warnings about attributing incorrect/unsound statements to him. For example, here are some very commonly-quoted ahadith, which actually vary tremendously in their degree of authenticity from the Prophet (may Allah bless him and grant him peace):
