Abdullah bin Amr bin As reported,
I heard the Messenger of Allah ﷺ say, "The first group to enter Paradise will be the poor among the Muhajirun, those through whom calamities are warded off. When they are commanded, they listen and obey. If one of them has a need before the ruler, it is not fulfilled until he dies with it still in his heart. On the Day of Resurrection, Allah 
will call to Paradise, and it will come forward with its ornaments and adornments, and He will say, 'Where are My servants who fought in My path, were killed in My path, were harmed in My path, and strove in My path? Enter Paradise.' So they will enter it without reckoning and without punishment." And he mentioned the rest of the hadith.
Ahmad 6571
Sahihحدثنا حسن حدثنا ابن لهيعة حدثنا أبو عشانة أنه سمع
عبد الله بن عمرو يقول
سمعت رسول الله ﷺ يقول إن أول ثلة تدخل الجنة لفقراء المهاجرين الذين يتقى بهم المكاره وإذا أمروا سمعوا وأطاعوا وإذا كانت لرجل منهم حاجة إلى السلطان لم تقض له حتى يموت وهي في صدره وإن الله عز وجل يدعو يوم القيامة الجنة فتأتي بزخرفها وزينتها فيقول أي عبادي الذين قاتلوا في سبيلي وقتلوا وأوذوا في سبيلي وجاهدوا في سبيلي ادخلوا الجنة فيدخلونها بغير حساب ولا عذاب وذكر الحديث

Its isnad is sahih, and it carries the same meaning as the previous one, with a slight abridgment in some places and an addition in others. Hakim related it in Mustadrak 3:71–72, via Muhammad bin Abdullah bin Abdul-Hakam, from Ibn Wahb, from Amr bin Harith, that Abu Ushana Maafiri told him that he heard Abdullah bin Amr bin As, and he mentioned it in full, then said, "A hadith with a sahih isnad, though the two of them did not narrate it," and Dhahabi agreed with him.Ibn Kathir mentioned it in his Tafsir 4:519, quoting Tabarani, via Ahmad bin Salih, from Ibn Wahb, from Amr bin Harith. It occurs there as Amr bin Harith, which is a printing error.Haythami mentioned it in Majma al-Zawaid 10:259, referring to this same place, and said, "Ahmad and Tabarani related it," and he added to it, then he cited the rest of its wording as found in Tabarani, and said, "The men of Tabarani's chain are the men of sahih narrations, except for Abu Ushana, who is trustworthy."Suyuti quoted it in Durr Manthur 4:57–58 with wording that contains some abridgment and adaptation, combining parts of this narration with the one before it. He also attributed it to Ibn Jareer, Ibn Abu Hatim, Ibn Hibban, Abu Shaykh, Ibn Mardawayh, and Bayhaqi in Shuab al-Iman.As for his saying, "O My servants," the "O" is simply a vocative particle, as is clear. In some of the sources we referred to, it reads, "Indeed, My servants," which is a variant confirmed in the margin of manuscript M. In others it reads, "Where are My servants!" which I think is a distortion or a scribal error.
