This hadith has been narrated on the authority of Ibn 'Umar through another chain of transmitters.

Yahya ibn Yahya narrated to us, he informed us: Hammad ibn Zayd, from Mu'alla ibn Ziyad, from Mu'awiyah ibn Qurrah, from Ma'qil ibn Yasar, that the Messenger of Allah, peace and blessings be upon him... And Qutaybah ibn Sa'id narrated to us, Hammad narrated to us, from al-Mu'alla ibn Ziyad, who traced it back to Mu'awiyah ibn Qurrah, who traced it back to Ma'qil ibn Yasar, who traced it back to the Prophet, peace and blessings be upon him, who said: "Worship during turmoil is like emigration to me."

The previous hadith is narrated through Abu Kamil from Hammad with the same chain.

Anas bin Malik (RA) reported that a person asked Allah's Apostle (ﷺ) : When would the Last Hour come? Thereupon Allah's Messenger (ﷺ) kept quiet for a while, then looked at a young boy in his presence belonging to the tribe of Azd Shanilwa and he said: If this boy lives he would not grow very old till the Last Hour would come to you. Anas said that this young boy was of our age during those days.
