Jabir bin Abdullah reported,

Tufayl bin Amr al-Dawsi came to the Prophet ﷺ and said, "Messenger of Allah, would you like a strong, well-fortified stronghold with protection?" This referred to a fortress that belonged to the tribe of Daws during the days of ignorance. But the Prophet ﷺ declined, for Allah had reserved that honor for the Ansar.When the Prophet ﷺ migrated to Madinah, Tufayl bin Amr migrated to join him, and a man from his tribe migrated with him. They found the climate of Madinah unhealthy, and the man fell ill. He grew distressed, took some broad arrowheads he had, and cut his finger joints with them. His hands gushed blood until he died.Tufayl bin Amr later saw him in a dream, looking well in appearance, but with his hands covered.Tufayl asked him, "What did your Lord do with you?"He replied, "He forgave me because of my migration to His Prophet ﷺ."Tufayl asked, "Why do I see you covering your hands?"He answered, "I was told, 'We will not restore for you what you yourself ruined.'"Tufayl related this to the Messenger of Allah ﷺ, and the Messenger of Allah ﷺ said, "O Allah, and forgive his hands as well."

عن جابر

أن الطفيل بن عمرو الدوسي أتى النبي ﷺ فقال يا رسول الله! هل لك في حصن حصين ومنعة؟ (قال حصن كان لدوس في الجاهلية) فأبى ذلك النبي ﷺ، الذي ذخر الله للأنصار. فلما هاجر النبي ﷺ إلى المدينة هاجر إليه الطفيل بن عمرو. وهاجر معه رجل من قومه. فاجتوؤا المدينة، فمرض، فجزع، فأخذ مشاقص له، فقطع بها براجمه، فشخبت يداه حتى مات. فرآه الطفيل بن عمرو في منامه فرآه وهيئته حسنة. ورآه مغطيا يديه. فقال له: ما صنع بك ربك؟ فقال: غفر لي بهجرتي إلى نبيه ﷺ. فقال: ما لي أراك مغطيا يديك؟ قال: قيل لي: لن نصلح منك ما أفسدت. فقصها الطفيل على رسول الله ﷺ فقال رسول الله ﷺ: اللهم! وليديه فاغفر.
