Alms - Al sadakat - are one of the really needed deeds we all should do as it's so clear in the following verses from Sorat At-Taubah.
وَآخَرُونَ اعْتَرَفُواْ بِذُنُوبِهِمْ خَلَطُواْ عَمَلاً صَالِحاً وَآخَرَ سَيِّئاً عَسَى اللّهُ أَن يَتُوبَ عَلَيْهِمْ إِنَّ اللّهَ غَفُورٌ رَّحِيمٌ - 102- خُذْ مِنْ أَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلاَتَكَ سَكَنٌ لَّهُمْ وَاللّهُ سَمِيعٌ عَلِيمٌ - 103 - أَلَمْ يَعْلَمُواْ أَنَّ اللّهَ هُوَ يَقْبَلُ التَّوْبَةَ عَنْ عِبَادِهِ وَيَأْخُذُ الصَّدَقَاتِ وَأَنَّ اللّهَ هُوَ التَّوَّابُ الرَّحِيمُ - 104 - التوبة
And others have confessed their faults, they have mingled a good deed and an evil one; may be Allah will turn to them (mercifully); surely Allah is Forgiving, Merciful. - 102 - Take alms out of their property, you would cleanse them and purify them thereby, and pray for them; surely your prayer is a relief to them; and Allah is Hearing, Knowing. - 103 - Do they not know that Allah accepts repentance from His servants and takes the alms, and that Allah is the Oft-returning (to mercy), the Merciful? - 104 - At-Taubah
