However, he did not stay in India for long, instead starting a period of worldwide travelling. In 1931, he held a speech at the World Islamic Congress in Jerusalem, where he praised Finland for its friendly attitude towards Muslim émigrés from Russia. He also visited Ankara, Berlin (where he founded an Islamic publishing house), Finland and Iran and Iraq, where he studied Shia Islam. He resumed his tour in 1937, again visiting India, more specifically Bombay and Benares. He was then invited by Abdurreshid Ibrahim to Japan; the two travelled together to China, Java, Sumatra and Singapore.
