Ali said that al-'Abbas asked God’s messenger about paying his <i>sadaqa</i> in advance before it became due, and he gave him permission to do that. Abu Dawud, Tirmidhi, Ibn Majah and Darimi transmitted it.

وَعَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ: أَنَّ الْعَبَّاسَ سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي تَعْجِيل صَدَقَة قَبْلَ أَنْ تَحِلَّ: فَرَخَّصَ لَهُ فِي ذَلِكَ. رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَابْنُ مَاجَهْ وَالدَّارِمِيُّ
