Ibn Mas'ud (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said: "The people who will be nearest to me on the Day of Resurrection will be those who supplicate Allah more often for me."

[At-Tirmidhi].

وعن ابن مسعود رضي الله عنه أن رسول الله ﷺ قال: “أولى الناس بي يوم القيامة أكثرهم علي صلاة" رواه الترمذي وقال حديث حسن.
