Shurahbil bin Shafaa reported,
One of the companions of the Prophet ﷺ reported that he heard the Prophet ﷺ say, "On the Day of Resurrection, the children will be told, 'Enter Paradise.'They will say, 'Our Lord, not until our fathers and mothers enter.'So they will come, and Allah 
will say, 'Why do I see them holding back? Enter Paradise.'They will say, 'Our Lord, our fathers and mothers.'So He will say, 'Enter Paradise, you and your parents.'"
Ahmad 16971
Sahihحدثنا أبو المغيرة حدثنا حريز قال
حدثنا شرحبيل ابن شفعة
عن بعض أصحاب النبي ﷺ أنه سمع النبي ﷺ يقول يقال للولدان يوم القيامة ادخلوا الجنة قال فيقولون يا رب حتى يدخل آباؤنا وأمهاتنا قال فيأتون قال فيقول الله عز وجل ما لي أراهم محبنطئين ادخلوا الجنة قال فيقولون يا رب آباؤنا وأمهاتنا قال فيقول ادخلوا الجنة أنتم وآباؤكم
Its isnad is sahih. Hurayz is Ibn Uthman Rahbi Himsi, who is trustworthy and firmly established, and he has come up many times before. Shurahbil bin Shafah Shami is reliable, Ibn Hibban confirmed his trustworthiness, and Abu Dawud said, "The teachers of Hurayz are all trustworthy." Haythami mentioned the hadith in 10/383 and said, "Its narrators are the narrators of the Sahih except for Shurahbil, and he is trustworthy."Ibn Majah narrated it with similar wording under number 1609, "The stillborn child will drag his mother by his umbilical cord into paradise," and Ibn Abu Shayba narrated something similar under 3543. The wording we have here is more sahih, and it did not specify whether the parents are Muslim or not, but in Ibn Majah and Ibn Abu Shayba it is restricted to Islam, and perhaps this applies when the Muslim person reckons his child with his Lord.
