- Incomplete documentation: Ibn al-Salah criticized the Sunni method of hadith authentication for its reliance on incomplete documentation, which can lead to errors and inaccuracies in the transmission and authentication of hadiths. However, Ibn Hajar al-Asqalani, a medieval Islamic scholar, rebutted this criticism by noting that the science of hadith includes the examination of the chain of narrators (Isnad), the content of the hadith (Matn), and the study of the circumstances of the narrators, which helps to compensate for any potential gaps in documentation.
- Over-reliance on the chain of narrators: Muhammad Abduh criticized the Sunni method of hadith authentication for its over-reliance on the chain of narrators rather than the content of the hadith. However, scholars such as Ibn al-Salah and al-Nawawi have argued that the chain of narrators is important because it provides a way to trace the authenticity of a hadith back to its source, and helps to establish the reliability and credibility of the narrators.
- Political and sectarian bias: Sayyid Ahmad Khan accused Sunni scholars of being politically or sectarian biased in their authentication of hadiths, leading to the acceptance or rejection of hadiths based on their compatibility with their own beliefs or affiliations. However, scholars such as Ibn Taymiyyah and Ibn Hajar al-Asqalani have argued that the science of hadith includes rigorous standards and criteria for authentication that are independent of personal beliefs or affiliations.
- Lack of consistency: Shabbir Akhtar has criticized the Sunni method of hadith authentication for its lack of consistency in applying the principles of authentication, leading to different scholars reaching different conclusions about the authenticity of the same hadith. However, scholars such as Ibn al-Salah and al-Nawawi have argued that there is a high degree of consensus among Sunni scholars about the authenticity of the major hadith collections, and that differences of opinion on minor hadiths are natural and expected.
- Ignoring the context: Fazlur Rahman argued that the Sunni method of hadith authentication does not adequately take into account the context in which the hadith was narrated or the changes in the language and culture over time. However, scholars such as Ibn al-Salah and Ibn Hajar al-Asqalani have noted that the science of hadith includes the study of the narrators, their background, and their reliability, which helps to provide context for the hadiths.
