يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةًۭ ۚ ذَٰلِكَ خَيْرٌۭ لَّكُمْ وَأَطْهَرُ ۚ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌ
O ye who believe! When ye hold conference with the messenger, offer an alms before your conference. That is better and purer for you. But if ye cannot find (the wherewithal) then lo! Allah is Forgiving, Merciful.

Narrated Abu Huraira:
I heard Allah's Messenger (ﷺ) saying "From among my followers, a group (o 70,000) will enter Paradise without being asked for their accounts, Their faces will be shining like the moon." 'Ukasha bin Muhsin Al-Asadi got up, lifting his covering sheet and said, "O Allah's Messenger (ﷺ) Invoke Allah for me that He may include me with them." The Prophet (ﷺ) said! "O Allah! Make him from them." Then another man from Al-Ansar got up and said, "O Allah's Messenger (ﷺ)! Invoke Allah for me that He may include me with them." On that Allah's Messenger (ﷺ) said, "'Ukasha has anticipated you."
