"I heard Abu Hurairah say: 'I came back (from a journey) with the Messenger of Allah ﷺ and he heard a man reciting 'Say: He is Allah, (the) One, Allah-us-Samad (the Self-Sufficient Master). He begets not, nor was He begotten. And there is none equal or comparable unto Him.' The Messenger of Allah ﷺ said: 'It is guaranteed.' We asked him: 'What, O Messenger of Allah?' He said: 'Paradise.'" (Using translation from Nasāʾī 994)
سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ أَقْبَلْنَا مَعَ رَسُولِ اللهِ ﷺ فَسَمِعَ رَجُلًا يَقْرَأُ {قُلْ هُوَ اللهُ أَحَدٌ اللهُ الصَّمَدُ لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ} [الإخلاص 2] فَقَالَ رَسُولُ اللهِ ﷺ «وَجَبَتْ» فَسَأَلْتُهُ مَاذَا يَا رَسُولَ اللهِ؟ فَقَالَ «الْجَنَّةُ»
