abu omar aldharee narrated that the leader of the atoms is the pioneer who goes out first to something he has smelled without his companions due to a special quality that god almighty has given him and the delicacy of his senses. so if he tries to carry it and tries to transport it and is unable to do so after his excuse wears out he comes to them and informs them then returns and it goes out after him like an extended black thread. and no atom ever meets another atom except that it stops it and tells it something then turns away from it.
وروى أبو عمر الضرير، أن رئيس الذر الرائد الذي يخرج أولا لشيء قد شمه دون أصحابه، لخصوصية خصه الله تعالى بها، ولطافة الحس، فإذا حاول حمله وتعاطى نقله، وأعجزه ذلك بعد أن يبلى عذرا، أتاهن فأخبرهن فرجع، وخرجت بعده كأنها خيط أسود ممدود. وليست ذرة أبدا تستقبل ذرة أخرى إلا واقفتها وسارتها بشىء ثم انصرفت عنها.
