Hadith.1968 - Ali ibn Abi Hamzah narrated from Abu Basir, who said
"I asked Abu Abdullah (as) about traveling once the Month of Ramadan has begun.
Imam (as) said: 'Do not [travel], except in cases I will inform you of: traveling to Mecca, waging battle in the way of Allah (swt) Almighty, preserving wealth you fear will perish, or saving a brother you fear will face destruction—and he is not a brother from the same father and mother.'"
