A companion of the Messenger of Allah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Every Surah has its portion from bowing (ruku) and prostration (sajdah). And in another narration: Give every Surah its portion from bowing and prostration. ‘Asim says: Later I met Abu Al-‘Aliyah and said to him: Sayyiduna ‘Abdullah ibn ‘Umar (may Allah be pleased with him) used to recite several Surahs in one rak‘ah; do you know who narrated this hadith to you? He said: There is no doubt that I know it, and I even know how long it has been since he narrated this hadith to me; he narrated this hadith to me fifty years ago.
