Mahumud's biographers notice in many instances the strict observance of the Sabbath, at the period in which he flourished; they also say he selected Friday to be observed as the Mussulmaun Sabbath in distinction from the Jews, who it would seem were jealous of Mahumud's teaching, and annoyed both him and his followers in every way they could possibly devise. And the Khoraun commentators, on the subject of Mahumud's mission, declare, when speaking of the place to which the Mussulmaun bow in prayer, 'That when Mahumud first commenced his task of teaching the ignorant Arabians to forsake their idol worship, and to turn to the only true God, he was often reviled and insulted by the Jews; who even ridiculed the presumption of the Mussulmauns in daring to bow down, in their worship, towards Jerusalem, in the same direction with them. Mahumud was sadly perplexed whether to abstain or continue the practice, as he was unwilling to offend the Jews: in this trial he was visited by the angel Gabriel, who brought the following command to him from God:-- 'Turn from Jerusalem; and when thou bowest down to Me, face that Holy House of Abraham, the place of sacrifice: that shall be thy Kiblaah, O Mahumud.' Kiblaah is the point to which men bow in worship.[12] Kaabah is the 'Holy House' where Abraham's sacrifice was offered. Mecca is the city or tract of country surrounding the house. Thus they will say: 'I am making my pilgrimage to Mecca, to visit the Kaabah, which in my Namaaz, has been my Kiblaah when worshipping my God.' A Commentator on the Khoraun writes, in allusion to the prevailing worldly-minded men of his day, the following expressive definition of the objects most worshipped by them, and concludes with the one only Kiblaah deserving men's attention. 'The Sovereign's Kiblaah is His well-ornamented crown.' 'The Sensualist's Kiblaah, The gratification of his appetites.' 'The Lover's Kiblaah, The mistress of his heart.' 'The Miser's Kiblaah, His hoards of gold and silver.' 'The Ambitious Man's Kiblaah, This world's honours and possessions.' 'The mere Professor's Kiblaah, The arch of the Holy House.' And 'The Righteous Man's Kiblaah, The pure love of God,--which may all men learn and practise.' The Mussulmaun Faith directs them to believe, not only in the prophets and their writings, but also that they are intercessors at the throne of grace; for this reason Mahumud taught his followers to call on God to hear them for the sake of,-- '1st. Adam, Suffee Ali ("the Pure" is the nearest possible translation).' '2nd. Noah, the Prophet of God.' '3rd. Abraham, the Friend of God.' '4th. Moses, who Conversed with God.' '5th. Jesus, the Soul of God.' '6th. Mahumud, the Prophet of God.'[13]
