Ubada bin Samit reported,

Ubayy bin Kaab said, "The Messenger of Allah ﷺ taught me a verse, and I heard another man recite it differently from how I had been taught. I asked him, 'Who taught you this recitation?'He replied, 'The Messenger of Allah taught it to me.'I said, 'By Allah, the Messenger of Allah taught it to me in such-and-such a way.'"Ubayy continued, "No doubt about Islam ever stirred within me as it did that day. So I went to the Prophet ﷺ and said, 'Messenger of Allah, did you not teach me such-and-such a verse in this way?'He answered, 'Yes.'I said, 'But this man claims that you taught it to him in another way.'He then struck his hand upon my chest, and the doubt left me, and I never felt anything of it again. Then the Messenger of Allah ﷺ said, 'Jibreel and Mikail came to me. Jibreel said, "Recite the Quran in one mode."Mikail said, "Ask for more."Jibreel said, "Recite it in two modes."Mikail said, "Ask for more," until he reached seven modes. Then Jibreel said, "Each is healing and sufficient."'"

عن عبادة بن الصامت

أن أبي بن كعب، قال: أقرأني رسول الله ﷺ آية، وأقرأها آخر غير قراءة أبي، فقلت: من أقرأكها؟ قال: أقرأنيها رسول الله، قلت: والله لقد أقرأنيها كذا وكذا، قال أبي: فما تخلج في نفسي من الإسلام ما تخلج يومئذ، فأتيت النبي ﷺ، قلت: يا رسول الله، ألم تقرئني آية كذا وكذا؟ قال: بلى. قال: فإن هذا يدعي أنك أقرأته كذا وكذا، فضرب بيده في صدري، فذهب ذاك، فما وجدت منه شيئا بعد، ثم قال رسول الله ﷺ: أتاني جبريل وميكائيل، فقال جبريل: اقرأ القرآن على حرف، فقال ميكائيل استزده، قال: اقرأه على حرفين، قال: استزده حتى بلغ سبعة أحرف، قال: كل شاف كاف
