Guru Nanak Dev ji standing in the midst of devotees

Guru Nanak Dev is standing in the middle of an open courtyard of Sultanpur Lodi Mosque where everyone bends to do Namaz. When Guru Nanak was asked why he had not joined them, he mentioned there is no point in only doing the ritual as the ruler was thinking of his horse bought in Kabul and the Quazi was concerned about his newly born calf.
