من كره أن يركع دون الصفThose who consider ruku before joining the row to be disliked
Hadith 2659
٢٦٥٩ - حدثنا يحيى بن سعيد عن محمد بن عجلان عن الأعرج عن أبي هريرة قال: إذا دخلت (١) والإمام راكع فلا تركع حتى تأخذ مقامك من الصف (٢).
Hazrat Abu Hurairah says that when you enter the mosque and the Imam is in the state of bowing (ruku‘), do not say the takbeer until you join the row. Hazrat Abu Bakr says that if there is another person with him, he may perform ruku‘ before joining the row, but if he is alone, he should not perform ruku‘.
