allah's messenger (pbuh) used to deliver sermons standing by an old palm tree trunk. when a pulpit was made for him he used it instead. the trunk then started moaning with a sound heard by all the attendants in the mosque. allah's messenger (pbuh) went down the pulpit interrupting his sermon, held the trunk and said "calm down, calm down trunk, if you wish i could plant you and you would turn green and would be fruitful till the day of judgment or if you wish i could burry you and you would be my partner in the hereafter. the trunk replied "i want to be buried and to be your companion in the hereafter”. anas ibn malik (may allah be pleased with him) said: when allah's messenger (pbuh) died we used to say " o allah's messenger a trunk which you left yearned your absence, now that you left us, aren’t our hearts supposed to yearn for you.
