“Saturdays are for deceit and trickery. Sundays are for planting and building. Mondays are for war and bloodshed. Tuesdays are for traveling and making requests. Wednesdays are for pessimism and bad omen. Thursdays are for visiting the chiefs and Fridays are for proposing to marry and getting married.”The compiler of the book - may God be pleased with him - said, ‘Monday is the day for traveling to where you pray to God for rain.’
