What advice would you like to Give to the Muslim Ummah?

The Messenger of Allah (saw) said, "The Faithful are to one another like [parts of] a building - each part strengthening the others" and "Every Muslim is a brother to a Muslim, neither wronging him nor allowing him to be wronged. And if anyone helps his brother in need, Allah will help him in his own need; and if anyone removes a calamity from [another] Muslim, Allah will remove from him some of the calamities of the Day of Resurrection; and if anyone shields [another] Muslim from disgrace, Allah will shield him from the disgrace on the Day of Resurrection." [Al-Bukhari and Muslim, on the authority of `Abd Allah ibn `Umar].
