[UNPUBLISHED]
PER CURIAM.
Iowa inmate Darwin Walden appeals from the adverse grant of summary judgment entered by the District Court in this 42 U.S.C. § 1988 action. After careful de novo review, see Anderson v. Larson, 327 F.3d 762, 767 (8th Cir.2003), we conclude that summary judgment was proper because Walden failed to raise a material factual issue on whether defendants substantially burdened his ability to practice Islam, see Patel v. U.S. Bureau of Prisons, 515 F.3d 807, 813-14 (8th Cir.2008). Accordingly, we affirm the judgment of the District Court. See 8th Cir. R. 47B.
. The Honorable Linda R. Reade, Chief Judge, United States District Court for the Northern District of Iowa.
