The Prophet ﷺ said, "Whoever stores up provisions in this world will benefit from them in the next."
عن النبي ﷺ قال: من يتزود في الدنيا ينفعه في الآخرة.

Tabarani reported it in Mujam al-Kabir (2/345-346) from Abdan bin Ahmad (that is, Abdullah bin Ahmad bin Musa, Abdan being his nickname), who said, Hisham bin Ammar narrated to us, who said, Marwan bin Muawiya narrated to us, from Ismail bin Abu Khalid, from Qays (that is, Ibn Abu Hazim), from Jareer, who said, then he mentioned the hadith. Its isnad is hasan because of Hisham bin Ammar bin Nusayr Sulami, for his hadith is hasan. Haythami said in Majma (10/311), "Tabarani reported it, and its narrators are the narrators of sahih."His saying, "Whoever provides for himself in this world," means from righteous deeds.Of similar meaning is what was narrated from Shaddad bin Aws, who said, the Messenger of Allah ﷺ said, "The shrewd one is he who calls himself to account and works for what comes after death, while the helpless one is he who follows his soul's desires and merely hopes in Allah."Tirmidhi (2459), Ibn Majah (4260), Ahmad (17123), and Hakim (1/57) all reported it, all of them through the route of Abu Bakr bin Abu Maryam Ghassani, from Damra bin Habib, from Shaddad bin Aws, who mentioned it. Tirmidhi said, "This is a hasan hadith." Hakim said, "This is a hadith that is sahih according to the criterion of Bukhari." Dhahabi followed up on this, saying, "No, by Allah, Abu Bakr is weak."I say, this is as he said, for Abu Bakr bin Abdullah bin Abu Maryam Ghassani is daif by consensus of the scholars, because thieves accosted him and took his belongings, and his mind became confused afterward, as Abu Hatim said. So perhaps this saying belongs to one of the righteous people and was mistakenly attributed to the Prophet ﷺ.It has another route from Shaddad bin Aws in Tabarani's Mujam al-Kabir (7141), and in its isnad is Amr bin Bakr Saksaki, who is discarded.Tirmidhi said, "The meaning of his saying, 'whoever calls himself to account,' is that he holds himself accountable in this world before he is held accountable on the Day of Resurrection. It is narrated that Umar bin Khattab said, 'Hold yourselves accountable before you are held accountable, and adorn yourselves for the greatest presentation.' The reckoning on the Day of Resurrection is only lightened for one who held himself accountable in this world. And it is narrated from Maymun bin Mihran, who said, 'The servant is not truly pious until he holds himself accountable as he would hold his partner accountable, asking from where his food and clothing come.'"
