"when one of you prostrates, let him not kneel as the camel kneels, but let him place his hands before his knees." This ḥadīth has been authenticated by a number of ḥadīth scholars, including ʿAbd al-Ḥaqq al-Ishbīlī and al-Shaykh al-Nawawī, and it was strengthened by al-Ḥāfiẓ in "al-Fatḥ" (2/291) and in "Bulūgh al-Marām." They are aware that the meeting between al-Nafs al-Zakiyyah and Abū al-Zinād is not known, as Imām al-Bukhārī pointed out in the biography of (al-Nafs al-Zakiyyah) in "al-Tārīkh al-Kabīr" (1/1/139): "I do not know whether he heard from Abū al-Zinād or not." I say: Thus, the researcher finds in the books of ḥadīth authentication dozens, even hundreds, of ḥadīths that have been authenticated by the scholars and ḥadīth experts, relying on contemporaneity without adhering to the condition of a meeting. This is only due to their conviction that this condition is one of perfection, not a condition of authenticity. If it is fulfilled, then excellent; if not, then contemporaneity is a blessing and suffices. This was the practice of the predecessors, as explained by Imām Muslim in his "Introduction," and the successors among the ḥadīth scholars, some of whom we have named, followed them in this. Muslim strongly criticized those who opposed them out of zeal for the purified sunnah and fear that something might be lost from it. The examples we have presented support his view, may Allāh have mercy on him. And with Allāh is success.
