lease can someone suggest where I can get an halal loan with no interest of like 400k to expand business?

Allah has made it haram to collect interest based loan.

Muslim narrated (1598) that Jaabir (may Allah be pleased with him) said: The Messenger of Allaah (blessings and peace of Allaah be upon him) cursed the one who consumes riba and the one who pays it, the one who writes it down and the two who witness it, and he said: they are all the same.

And the Prophet (blessings and peace of Allah be upon him) said: “A dirham of riba that a man consumes knowingly is worse before Allah than thirty-six acts of zina (adultery). Narrated by Ahmad and al-Tabaraani; classed as saheeh by al-Albaani in Saheeh al-Jaami‘, no. 3375

Jazak Allah Khairan
